1 To Insert AS Origin field into APNIC IP address database Xing Li Shuang Zhu CERNET

2 Problem Statement  APNIC’s IRR service APNIC needs to provide  Wrong IP prefix announcement in the BGP routing table from PA (holes) Make chaos in the global routing table (-:  Distinction of PA and PI IP blocks How about based on AS origin?

3 Example BGP routing table entry for /15, version Paths: (2 available, best #2) Advertised to peer-groups: rr-pop , (aggregated by ) (metric ) from ( ) Origin IGP, metric , localpref 100, valid, internal, atomic-aggregate Community: 2548: : : , (aggregated by ) (metric ) from ( ) Origin IGP, metric , localpref 100, valid, internal, atomic-aggregate, best Community: 2548: : :153

4 Example BGP routing table entry for /21, version Paths: (2 available, best #2) Advertised to peer-groups: rr-pop (metric ) from ( ) Origin IGP, metric , localpref 100, valid, internal Community: 2548: : : (metric ) from ( ) Origin IGP, metric , localpref 100, valid, internal, best Community: 2548: : :153

5 Example of Current APNIC whois database inetnum: netname: SJTU-CN descr: Shanghai Jiaotong University country: CN admin-c: SW1-CN tech-c: ZG1-CN notify: changed: source: APNIC

6 Example of RA whois database route: /15 descr: CERNET Center Tsinghua University Central Bldg. Bejing P. R. China origin: AS4538 member-of: RS-COMM_NSFNET notify: mnt-by: MAINT-AS4538 changed: source: RADB

7 Suggestions AS origin  as a mandatory field in the APNIC whois database  as a required procedure for the IP address application

8 Example inetnum: netname: SJTU-CN descr: Shanghai Jiaotong University country: CN origin: AS4538 admin-c: SW1-CN tech-c: ZG1-CN notify: changed: source: APNIC

9 Suggested Application Form #[NETWORK TEMPLATE V:5.0]# netname: descr: country: origin: admin-c: tech-c: remarks: changed: mnt-by: source: APNIC

10 Comments  Provide APNIC’s “IRR lit” service APNIC is the Authority  Define PA and PI based on AS origin Owns AS = PI, upper-stream’s AS = PA  Check of the immediate use of IP address Own AS or upper-stream’s AS  Evaluate Confederation membership number of AS

11 Questions? 
