The Asia Pacific Regional Registry APNIC has, as of today, begun to ration IPv4 addresses. Down to its last /8 block (around 16 million addresses) APNIC will now only be issuing existing users with /22 blocks of 1,024 addresses and is urging its customers to accelerate their adoption of IPv6.
European registry, RIPE, is expected to be down to its last /8 sometime this summer. In the UK around 60% of LIRs (Local Internet Registry) have yet to even apply for their allocation of IPv6 – check out the stats here.
