Disclaimer • Used to work for one of the regional registries (RIPE NCC) • No longer working for RIPE NCC • Only talking on my own behalf - not officially representing RIPE NCC • Things may have changed since I left; YMMV, objects in the mirror…
What is a registry • Assignment and registration of globally unique numbers needed to build Internet networks • IP numbers • AS numbers • DNS names provided by other registry • In past, InterNIC provided names & numbers in USA • Now split up (ARIN, Network Solutions)
What is a registry (con) • Trying to assign limited amount of space in a responsible and fair manner • Not only need to address address space depletion, but also restrictions in routing technology • These days, routing restrictions more important than depletion • Must be impartial; use objective means for request evaluation
What is a registry (con) • Lobby with government bodies (sigh) • This talk focuses on RIPE NCC • Details may be different for other registries • Overview only; RIPE provides training
The big picture ICANN ARIN RIPE NCC APNIC ISP1 ISP 2 ISP3
So you want address space? • Limited amount of address space globally available • Address space NOT depleted • Stories about death of Internet exaggerated • Need to motivate address space request • Using addressing plan
Addressing plan • List of amount of hosts (now, 1yr, 2yr) per subnet • Used to determine subnet size • Used to check deployment plans • Provide better documentation on network plans • No longer enough to claim to build large network without providing details
Aggregation & reservation • People want to reserve space for future expansion • Almost never works out the way it was planned • People want to reserve space for aggregation • With 70K routes on global Internet (and aggregating the address space on your borders), not sure how this is useful
Reservation does not work • If reservation too liberal, then address space wasted • Very few class B’s are close to effective utilization today • If reservation too strict, then need additional space • Negates the aggregation argument
Aggregation & route filtering (RIPE NCC) • When becoming a registry, NCC will allocate a /19 prefix • You can start announcing /19 • will get past prefix length filters • Upon proper motivation & approval, address space will be assigned • From your /19 allocation • Hence proper aggregation
So you want an AS-number? • Need to document who you’re peering with • Need to mention AS numbers of at least 2 peers • If AS number not known yet (starting an IX?), then document
So who controls the RIPE NCC? • RIPE NCC association controlled by board existing of RIPE NCC customers (actually, members) • So, RIPE NCC controls you, but you control RIPE NCC • Keeps organization impartial & neutral • Makes Internet industry self-governing
