I've finally convinced $DAYJOB to deploy IPv6. Justification for the IP space is easy, however the truth is that a /64 is more than we need in all locations. However the last I heard was that you can't effectively announce anything smaller than a /48. Is this still true?
Hi Jo, The short answer to your question is: /48 is the longest prefix from a direct RIR assignment that everyone currently accepts via BGP. /32 is the longest prefix from an ISP allocation that everyone currently accepts via BGP. As with IPv4 /24's, some folks accept longer prefixes. Not everyone.
Is this likely to change in the immediate future, or do I need to ask for a /44?
You need to ask for a /44. Regards, Bill Herrin -- William D. Herrin ................ herrin@dirtside.com bill@herrin.us 3005 Crane Dr. ...................... Web: <http://bill.herrin.us/> Falls Church, VA 22042-3004
