A Proposal for IPv4 Essential Infrastructure Address Policy SIG APNIC14, Kitakyushu, Japan 5 Sept 2002

Background and Problem No specific policy exists for infrastructure which is critical to Internet operation Resources for ‘critical infrastructure’ important to protect stability of core Internet functions Current policy regime only recognises ‘need’ rather than type of organisation Most critical infrastructure unlikely to qualify for routable address space allocation Addresses from upstream LIR: risk of widespread instability when renumbering

Proposal Allow portable addresses to be assigned to ‘critical infrastructure’ Minimum assignment of /24 “Critical Infrastructure” to be defined unambiguously Definition could change over time Address assignments specifically for servers and services comprising critical infrastructure Not for other purposes by receiving organisation

Proposal Continued Critical Infrastructure includes: Domain registry infrastructure (whois and DNS servers) Root DNS Generic top-level domain (gTLD) “Country Code” top-level domain (ccTLD) Address registry infrastructure (whois and reverse DNS servers) RIRs and NIRs IANA

Other RIRs ARIN RIPE NCC LACNIC ‘critical infrastructure’ assignments recognised to: ccTLD, gTLD, RIRs, IANA, IXes Recent modification: minimum assignment /24 RIPE NCC No special policy for critical infrastructure LIRs can request portable address space on behalf of their customers – no minimum size LACNIC No policy, but a proposal will be made at next policy meeting

Source of Address Space - Options Allocate a single large block for all assignments Allows easy configuration of ISP filters May be necessary to ensure routability More open to DOS attacks OR Use existing ‘swamp’ space Utilise existing free space Likely to be routable in small blocks Assignments not contiguous or easily recognisable

Implementation Secretariat to implement policy from three months after consensus Documentation Request forms and process Inform community Secretariat to report activity at future meetings Review of policy as needed Including definition of critical infrastructure
