The RIPE NCC received the AS Number block 30720 - 3174 from the IANA in September 2003.

I made a typo in my last message. The AS block is in fact 30720 - 31740.

A good example of why we need to stop announcing these allocations by ad-hoc email techniques and force IANA to operate an authoritative whois directory that identifies the current status of all AS number blocks and the entire IPv4 and IPv6 address spaces. Whether this is done with LDAP or DNS hacks or a simple machine parseable CSV file via HTTP is irrelevant. The fact is that we need a definitive and authoritative and machine-parseable source for this information. --Michael Dillon
