As of 14:40 today RIPE NCC have confirmed :-
"On Friday, 14 September 2012, the RIPE NCC, the Regional Internet Registry (RIR) for Europe, the Middle East and parts of Central Asia, distributed the last blocks of IPv4 address space from the available pool."
Obviously, having provided IPv6 for over 10 years, AAISP have been ready for this news. Whilst we have plans for conservation of remaining IPv4 addresses, we do plan to continue providing at least a static IPv4 external address to all new customers for some years to come, avoiding any 'Carrier Grade NAT' being needed within our network. New customers already receive an IPv6 assignment and pre-configured IPv6 router as standard.
The technicalities of the current IPv4 managent: We are reviewing all IPv4 usage and recovering any that can be reduced or reclaimed (customer and internal usage). We are advising customers of IPv6 usage where not currently deployed and where this could return some IPv4 space. The on-line ordering does not offer IPv4 blocks, but they can still be requested if needed.
