Policy Development Process (PDP) Flowchart Proposal Template Archive Movie https://www.arin.net/policy/pdp.html
39
PDP Origin - Rough Consensus The foundation of the PDP Rough consensus is a term used in consensus decision-making to indicate the "sense of the group" concerning a particular matter under consideration.* Note that 51% of the working group does not qualify as "rough consensus" and 99% is better than rough.* (*from wikipedia.org)
40
Consensus Decision Making* (*from wikipedia.org)
41
PDP Versions Current version is the 4 th First written version - April 2001 Two revisions Major overhaul - January 2009
42
The current PDP Empowers the Advisory Council as a development body (balanced by expanded petitions) Establishes goal = clear, technically sound and useful policy Requires staff and legal assessments and freezes text prior to Public Policy Meetings
43
Process Principles Open Forum - Anyone can participate Public Policy Mailing List Public Policy Meetings Transparent PDP documented Policies documented Meetings documented Bottom Up ARIN staff does not create policy, we apply it
44
PDP Roles Community Submit proposals! If there is a problem, raise it Comment on proposals (in favor or not?) Participate in Petitions Advisory Council “AC” (elected volunteers) Write the policy text to ensure that it is clear, technically sound and useful Determine Consensus
45
Roles cont. ARIN “Board” (elected volunteers) Provide process oversight Provide corporate fiduciary oversight ARIN Staff Provide feedback Clarity and Understanding Staff Assessments Implement Policy
46
Basic Steps 1.Community member submits a proposal 2.Community discusses the proposal on the “List” 3.AC creates a draft policy or abandons the proposal 4.Community discusses the draft policy on the “List” and at the meeting 5.AC conducts its consensus review 6.Community performs last call 7.Board adopts 8.Staff implements
47
Petitions Anyone dissatisfied with a decision by the AC can petition to keep the proposal moving forward 1.Petition to bring proposal to list and meeting 4 successful* 6 unsuccessful 2. Last call petition (to send to Board) 1 – unsuccessful *3 ultimately abandoned, 1 adopted

Case Study: Policy 2008-5
55
2008-5 Summary Name: Dedicated IPv4 block to facilitate IPv6 Deployment (2008-5) Proposal: Reserve some IPv4 space (a /10), and make it available to organizations that need some IPv4 space to deploy IPv6. Rationale: “[This policy] will facilitate IPv6 deployment by ensuring that some small chunks of IPv4 space will remain available for a long time to ease the co-existence of IPv4 & IPv6.”
56
Policy 2008-5 History Proposal was submitted on June 2008. Draft policy text discussed on the list and at ARIN XXII meeting (Oct 2008). The policy was sent to last call (Oct/Nov). Minor revision by the AC, reposted to last call Nov/Dec. Adopted by the Board 5 Jan 2009. Implemented 1 Apr 2009 (NRPM Section 4.10). https://www.arin.net/policy/proposals/2008_5.html
57
Policy Examples Adopted 2010-12: IPv6 Subsequent Allocation 2010-8: Rework of IPv6 assignment criteria 2010-2: /24 End User Minimum Assignment Unit 2010-1: Waiting List for Unmet IPv4 Requests (take what’s available or wait) Abandoned 2010-13: Permitted Uses of space reserved under NRPM 4.10 2010-7: Simplified IPv6 policy

Draft Policies and Proposals: Changes to Number Policy Einar Bohlin Policy Analyst
62
Draft Policies and Proposals 6 Active Draft Policies – 4 Awaiting Board Review – 2 Under Discussion 16 Policy Proposals
63
Draft Policies Awaiting Board Review ARIN-2011-3: Better IPv6 Allocations for ISPs – Nibble boundary allocations – IPv6 /36 to /12. ARIN-2011-4: Reserved Pool for Critical Infrastructure – IPv4 /16’s worth of space to be set aside for CI. ARIN-2011-5: Shared Transition Space for IPv4 Address Extension – Shared IPv4 /10 (eg. draft-shirasaki-nat444-03 ). ARIN-2011-6: Returned IPv4 Addresses – ARIN will quickly recycle address space in the ARIN region.
64
Draft Policies Under Discussion ARIN-2011-1: Globally Coordinated Transfer Policy – Would allow transfers to/from ARIN region The RIRs must have compatible transfer policy Need required (transfers are needs-based) ARIN-2011-7: Compliance Requirement – Primarily concerned with ensuring that ISPs maintain accurate reassignment information Enforcement via stopping reverse DNS services and possibly revocation
65
Proposals ARIN-prop-137 Global Policy for post exhaustion IPv4 allocation mechanisms by the IANA – Instructs IANA to accept returned address space and reissue that space to the RIRs (a 1/5 th portion to each RIR every 6 months). ARIN-prop-140 Business Failure Clarification – Changes policy text from “organization that goes out of business” to “organization that ceases to exist.” ARIN-prop-141 Combined M&A and Specified Transfers – Clarifies that organizations can perform both types of transfers at roughly the same time.
66
Proposals cont. 1 ARIN-prop-144 Remove Single Aggregate requirement from Specified Transfer – Removes “aggregate” language from the transfer policy (opposite of prop-153). ARIN-prop-146 Clarify Justified Need for Transfers – Extends the 12-month supply period for address space to all specified transfers. ARIN-prop-147 Set Transfer Need to 24 months – Lengthens the supply period for specified transfers to 24 months.
67
Proposals cont. 2 ARIN-prop-148 LRSA resources must not be transferred to LRSA – Requires the RSA for specified transfers of address space covered by an LRSA. ARIN-prop-149 Improved Transparency for Directed Transfers – Requires ARIN to publish a list of prefixes transferred via the policy for transfers to specified recipients. ARIN-prop-151 Limiting needs requirements for IPv4 Transfers – Removes the needs-based evaluation from transfers to specified recipients.
68
Proposals cont. 3 ARIN-prop-152 RSA Modification Limits – Regards transfers and the RSA. ARIN-prop-153 Correct erroneous syntax in NRPM 8.3 – Would change the transfer policy so that only a single aggregate could be transferred (opposite of prop 144).
69
Did any of those proposals possibly affect you? You have two ways to voice your opinion: – Public Policy Mailing List – Public Policy Meeting (in person or remote)

IPv4 Depletion IPv6 Adoption

Quick History of the Internet Protocol Internet Protocol version 4 (IPv4, or just “IP”) – First developed for the original Internet (ARPANET) in spring 1978 – Deployed globally with growth of the Internet – Total of 4 billion IP addresses available – Well entrenched and used by every ISP and hosting company to connect customers to the Internet – Allocated based on documented need Internet Protocol version 6 (IPv6) – Design started in 1993 when IETF forecasts showed IPv4 depletion between 2010 and 2017 – Completed, tested, and available for production since 1999 – Total of 340,282,366,920,938,463,463,374,607,431,768,211,456 IP addresses available – Used and managed similar to IPv4

IPv4 Depletion Situation Report Each RIR received its last /8 from IANA on 3 February 2011. The IANA free pool of IPv4 addresses has reached 0%. While each RIR currently has IPv4 addresses to allocate, it is impossible to predict when each RIR will run out. ARIN publishes an inventory of available IPv4 addresses, updated daily, at www.arin.net.
90
IPv4 & IPv6 - The Bottom Line We’re running out of IPv4 address space. IPv6 must be adopted for continued Internet growth. IPv6 is not backwards compatible with IPv4. We must maintain IPv4 and IPv6 simultaneously for many years. IPv6 deployment has begun.
91
RIRs have been allocating IPv6 address space since 1999. Thousands of organizations have received an IPv6 allocation to date. ARIN has IPv6 distribution policies for service providers, community networks, and end-user organizations. IPv6 Deployment has begun
92
IPv4 & IPv6 Coexistence Today, the Internet is predominantly based on IPv4. For the foreseeable future, the Internet must run both IP versions (IPv4 & IPv6) at the same time. (When done on a single device, this is called the “dual-stack” approach.) Deployment is already underway: Today, there are organizations attempting to reach your mail, web, and application servers via IPv6...
93
Action Plans What does this mean for: Broadband Access Providers? Internet Service Providers? Internet Content Providers? Enterprise Customers? Equipment Vendors? Government Organizations?
94
Call to Action Broadband Access Providers Your customers want access to the entire Internet, and this means IPv4 and IPv6 websites. Offering full access will require running IPv4/IPv6 transition services and is a significant engineering project. Multiple transition technologies are available, and each provider needs to make its own architectural decisions.
95
Call to Action Internet Service Providers Plan out how to connect businesses via IPv6- only and IPv4/IPv6 in addition to IPv4-only. Businesses are beginning to ask for IPv6 over their existing Internet connections and for their co-located servers. Communicate with your peers and vendors about IPv6, and confirm their timelines for production IPv6 services.
96
Call to Action Internet Content Providers Content must be reachable to newer Internet customers. Content served only via IPv4 will be accessed by IPv6 customers via transition solutions run by the access providers. Plan on serving content via IPv6 in addition to IPv4 as soon as possible.
97
Call to Action Enterprise Customers Mail, web, and application servers must be reachable via IPv6 in addition to IPv4. Open a dialogue with your Internet Service Provider about providing IPv6 services. Each organization must decide on timelines, and investment level will vary.
98
Call to Action Equipment Vendors There was probably limited demand for IPv6 in the past. Demand for IPv6 support will become mandatory very, very quickly. Introduce IPv6 support into your product cycle as soon as possible.
99
Awareness Coordinate with industry Adopt incentives Regulatory Economic Support and promote awareness and educational activities Require IPv6-compatibility in procurement procedures Officially adopt IPv6 Call to Action Government Organizations

107
New ARIN Online Functionality Reverse DNS Zone Management DNSSEC Resource Requests POC Validation
108
Reverse DNS Managed per zone, not per network Must manage through ARIN Online Networks issued without nameservers SWIP to customers, then add reverse delegation
109
Reverse DNS - Shared Authority Joe’s Bar and Grill has reassigned a /24 to HELLO WORLD. Both can manage the /24 zone.
110
Reverse DNS – Querying Whois Query for the zone directly: whois> 136.136.192.in-addr.arpa Name: 136.136.192.in-addr.arpa.

111
DNSSEC Same interface as reverse DNS DS records generated by user Zone must have nameservers before you can add DS records
112
1)Paste DS Record 2)Parse DS Record 3)Apply
113
IP/ASN Requests Done through ARIN Online only Officer attestation for IP requests now done via a signed form instead of email Can no longer specify resource POCs or reverse DNS delegation in request
114
Policy 2008-7: POC Validation Annual validation of each POC handle required Can validate either by email sent by ARIN or ARIN Online If linked to POCs that have not been validated within 60 days, can’t access ARIN Online until POC handles validated
115
Template Changes Version 5 templates – Version 4 still accepted – Version 3 and prior no longer accepted Resource request templates deprecated API key required to authorize processing – Generated via ARIN Online – Can associate an email address – Required for all templates
116
Version 5 Reassign Simple Template: ARIN-REASSIGN-SIMPLE-5.0 ** As of March 2011 ** Detailed instructions are located below the template. 00. API Key: 01. Registration Action (N,M, or R): 02. Network Name: 03. IP Address and Prefix or Range: 04. Origin AS: 05. Private (Yes or No): 06. Customer Name: 07. Customer Address: 08. Customer City: 09. Customer State/Province: 10.

117
Debugging Template Problems Most templates aren’t ticketed Problems? Send both template and error message to debug@arin.net debug@arin.net Designed to be backward compatible, but may be a few slight differences
118
RESTful Interface Programmatic way to interact with ARIN – Intended to be used for automation – Not meant to be used by humans Useful for ISPs that manage a large number of SWIP records Requires an investment of time to achieve those benefits
119
Example – Reassign Detailed Your automated system issues a PUT call to ARIN using the following URL: https://www.arin.net/rest/net/NET-10-129-0-0-1/reassign?apikey=API-1234-5678-9ABC-DEFG The call contains the following data: 4 HW-1 A Reassigned 10.129.0.0 10.129.0.255 24 NET-10-129-0-0-1 HELLOWORLD
120
Example – Reassign Detailed ARIN’s web server returns the following to your automated system: 4 Tue Jan 25 16:17:18 EST 2011 HW-1 NET-10-129-0-0-2 A Reassigned 10.129.0.0 10.129.0.255 24 NET-10-129-0-0-1 netName>HELLOWORLD Reg date and net handle added
121
Other RESTful Notes IPv6 Reassign Simple available only through the RESTful interface Cannot manage reverse DNS zones (yet) Still operating RESTful beta site as a test bed – Must request access
122
Obtaining RESTful Assistance “Ask ARIN” via your web account arin-tech-discuss mailing list – Make sure to subscribe – Someone on the list will help you ASAP Help Desk phone not a good fit – Debugging these problems requires a detailed look at the method, URL, and payload being used
123
Policy Changes 3 month supply for all ISPs IPv6 End User IPv6 ISP in the pipeline 2010-14 IPv6 Subsequent Allocations for Transitional Technology M&A Transfers
124
3 Month Supply For ISPs Prior to IANA IPv4 free pool depletion, experienced ISPs could get a 12 month supply Dropped to 3 month supply immediately upon IANA issuing its last 5 /8s Still computed based on demonstrated utilization rate Expectation should be coming back ~4 times a year for additional IP addresses
125
IPv6 End User Changes Before: Block size based on HD Ratio – Complex; used logarithms After: Block size based solely on number of sites within the end user’s network Number of SitesBlock Size Justified 1/48 2-12/44 13-192/40 193-3,072/36 3,073-49,152/32
126
Results of End User Policy Change Small uptick in large blocks, but majority still /48 Prefix Length% of assignments in the year prior to new policy % of assignments since new policy implemented /32-/350.35%2.14% /36-/391.04%5.00% /40-/436.60%7.14% /44-/4715.97%17.86% /4876.04%67.86%
127
2011-3: Better IPv6 Allocation for ISPs ARIN AC recommended adoption 5/24/2011 Still needs to be ratified by ARIN Board and have an implementation date scheduled Allows ISPs to have uniform subnets – Each “serving site” gets a block large enough to number the largest serving site – Must be nibble-aligned: /48, /44, /40, etc
128
2011-3 Example ISP A, a FTTP provider, has 37 PoPs – The largest PoP (New York City) has 1,084 customers ISP A wants to assign a /48 to each – /37 smallest block that has 1,084 /48s (2,048) – Each of the 37 PoPs gets a /36 (round to nibble) Smallest block that contains 37 /36s is a /30 (64 /36s) ISP A gets a /28 (round to nibble)
129
2010-14: Standardize IP Reassignment Registration Requirements To be implemented by 9/30/2011 Abuse contact now required New policies for ISPs with residential customers that dynamically draw IP addresses from pools – must submit SWIP information for each market area – must show 80% assigned with a 50-80% utilization rate across markets IPv6 /64 and larger static reassignments must be visible via SWIP/RWhois
130
IPv6 Subsequent Allocations for Transitional Technologies ISPs with an initial allocation for native IPv6 can request a separate block to be used for IPv4 -> IPv6 transitional technology – 6rd is the most common example, but the policy doesn’t specify a technology /24 maximum allocation – Allows a typical ISP to map a /56 to each of their existing IPv4 addresses in a 6rd deployment
131
2010-6: Simplified M&A Transfers Implemented 9/9/2010 If resources are no longer justified, ARIN will work with you to get back into compliance If resources underused, ARIN will work with you on a plan to regain compliance via growth or return
132
Inventory Report IANA IPv4 free pool now depleted – ARIN received its last /8 from IANA in mid- February At that time, ARIN had ~5.49 /8 equivalents in its free pool Daily inventory published on ARIN’s web site
133
Inventory updated daily @ 8PM ET
134
Burn Rate Since IANA Depletion
135
The Obvious Question How long will that free pool last? ARIN doesn’t make projections Why not? – Past performance doesn’t always predict the future – Potential game-changing requests – Projections are interpreted as assurances of availability To illustrate, here are three plausible scenarios of ARIN’s IPv4 free pool exhaustion
136
View #1: The Wide-Eyed Optimist Network operators are responsible and will use their existing IPv4 addresses more efficiently and implement IPv6 ASAP We see a drop in consumption rate Projection assumes utilization rate observed since IANA IPv4 depletion will continue – Warning: small sample size
137
Projecting the recent burn rate forward, the supply might last 5 years
138
View #2: Business As Usual Network operators are pragmatic They will continue to consume IPv4 addresses just as they did in the past Plans for dealing with depletion of ARIN’s IPv4 free pool are in development but will not be deployed until depletion actually occurs Projection assumes same burn rate as seen over the past few years
139
Projecting the average yearly burn rate forward, the supply might last 18 months
140
View #3: Hit The Panic Button Network operators will act in their own self interest A small number of large requests shifts the timeline dramatically Projection assumes two hypothetical “game-changing” requests – One ISP has an immediate need for a /8 to be deployed over three months, another has a need for a /8+/10 to be deployed over one month – Assume they are justified
141
Two game-changing requests drop the supply to 6 months

The Reality – We Have No Idea Network operators may: – become more efficient – continue to consume at the same rate – consume at a faster rate IPv4 availability cannot be guaranteed because IPv4 free pool exhaustion cannot be accurately predicted – Hence why you should migrate to IPv6 – Unless you intend to stop growing your business….
143
IPv4 Churn ARIN does get back IPv4 addresses through returns, revocations, and reclamations – Return = voluntary – Revoke = for cause (usually nonpayment) – Reclaimed = fraud or business dissolution From 1/1/2005 to 3/31/2011, ARIN got ~585 /16 equivalents back Hooray!
144
Unfortunately, we get back far less than we issue
145
IPv4 Holdings Profile 1.5% of the subscriber Org IDs hold 80% of the non- legacy IPv4 addresses The remaining 98.5% of the Org IDs hold 20% of the non-legacy IPv4 addresses
146
2010 Block Size Profile There were 162,644 /24s issued in 2010
147
Post-Depletion World While availability of IPv4 addresses cannot be assured, there will be ways network operators may be able to obtain additional IPv4 addresses – Transfers to Specified Recipients – Specified Transfer Listing Service (STLS) – Waiting List for Unmet IPv4 Requests
148
Transfers to Specified Recipients Resources no longer required to be under RSA If resources are not maintained under RSA, verification of title may take some time Attestation from officer required if resources not under LRSA/RSA RSA coverage = smoother transfer
149
STLS Previously had listers and needers “Facilitators” have been added – $100 annual fee for access Not much activity yet
150
2010-1: Waiting List for Unmet IPv4 Reqests Starts when ARIN can’t fill a justified request Option to specify smallest acceptable size If no block available between approved and smallest acceptable size, option to go on the waiting list May receive only one allocation every three months
151
Future Services RPKI in development – Cryptographically authenticate registration authority Routing registry changes – Better authentication (currently use only mail- from) Billing information visible through ARIN Online – View & modify billing contact information – View payment history
