1. Desired IRR Operational Model ~IRR/Whois Interaction~ Kuniaki Kondo (JPNIC IRR Workshop/IIJ) Ikuo Nakagawa (Intec) Takashi Arano (Asia Global Crossing)

2. JPNIC IRR Workshop What do we doing? Researching Current IRR status. Considering ideal IRR environment. Current IRR Problems Proposing IRR Environment How long do we do? 2 years. Current IRR workshop This workshop was closed at begin of this year. Currently, this workshop ’ s board members have been encouraging our proposal.

3. Focus of this presentation To ensure credibility of IRR database

4. Requirements for IRR Route/AS objects should be registered by only authorized persons. The system should not allow any un-authorized person to register others ’ routes (i.e. AS/prefixes). All announced routes should be registered ideally. Registered information should be up to date appropriately.

5. Current IRR problems(1) NO authorization mechanism exists for initial registration of route objects, that is, Any maintainer can register any object without authorization.

6. Current IRR problems(2) About 50% of “ full routes ” are not registered to public IRRs.

7. Observation Whois database and IRR database have very similar information.

8. Difference between IRR and Whois IRR Database of “ Routing Information ”. For operational purpose. Optional. Maintainers (ISP, in most cases) register objects. Whois Database of “ Administrative Information ”. For management purpose. Mandatory. IRs register objects when they allocate IP address blocks

9. Relation between IRR and Whois In simple case: Address Block IR ISP Allocation Announcement Prefix The Internet

10. Exception Case 1 – Split Allocated block Address Block IR ISP Allocation Announcement Prefix Split 2 or more Prefixes Prefix The Internet

11. Exception Case 2 – Punching Hole Address Block IR ISP-A Allocation Announcement Prefix-A Prefix-B The Internet ISP-B Punching Hole Assignment Prefix-A

12. Exception Case 3 – Historical Assignment Address Block IR ISP-A Announcement The Internet ORG. Assignment Prefix

13. Proposal : Authorized Registration In simple case: Address Block IR ISP Allocation Announcement Prefix The Internet IRR Registration Authorize AS Holder and IP Address holder are same organization.

14. Exception Case 1 – Split Allocated block Address Block IR ISP Allocation Announcement Prefix-APrefix-B Split 2 or more Prefixes Prefix-B Prefix-A The Internet IRR Registration Prefix-A and Prefix-B Authorize AS Holder and IP Address holder are same organization. IR authorizes registration of Prefix-A and Prefix-B, because ‘Address Block’ includes both of these prefixes.

15. Exception Case 2 – Punching Hole Address Block IR ISP-A Allocation Announcement Prefix-A Prefix-B The Internet ISP-B Punching Hole Prefix-A IRR Authorize Registration Prefix-A Registration Prefix-B Authorize AS Holder and IP Address holder are same organization. IR authorizes registration of Prefix-A, ISP-A authorizes registration of Prefix-B.

16. Exception Case 3 – Historical Assignment Address Block IR ISP-A Announcement The Internet ORG. Assignment Prefix IRR Authorize AS Holder and IP Address holder are possibly different organization. ⇒ Case by case. We need more discussion.

17. Example of IRR Operational Model RIRs maintain IRR databases, so that IRR database keep relation with Whois database

18. Considerations Whois databases must include AS number assignment information. How to treat historical assignment cases How does an ISP authorize a route for an IP address assigned to its customer Who is the authority of a route object? AS holder or IP address holder?

19. Current IRR Operation Where? Irr.iij.ad.jp How many does it mirror with. 24 IRR Servers including APNIC IRR Server. Has the proposed authorization model been working? No. We have to wait to implementation. We have to check scalability of our proposal. This activity will be done with APNIC IRR Project members.

20. How is APNIC IRR? It have a lot of IRR of Objects. When IRRd execute, It cannot read all IRR Objects. Because, Serial Number is overflow. IRR Authorization do not work on the IRRd.
