APNIC starts to ration IPv4 addresses #ipv6

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.

2 recent slash 8 allocations brings IPv4 x-day forward by 5 months

The Internet Assigned Numbers Authority (IANA) has just allocated regional registries RIPE and APNIC a /8 each this month.  For the uninitiated a /8 represents 2 to the power of 24 IP addresses or 167,77,216.

A /8 is the largest block allocation that can be made by IANA and these two have had the effect of bringing forward the x-date, the date for IPv4 exhaustion, by 5 months or so to April 30th 2011.

These blocks are subdivided into smaller subnets for further allocation to ISPs/organisations with smaller requirements  such as BT and Timico. Timico has a variety of block allocations ranging from  /16 to /20’s.

If you want to know more about IP addressing allocations check out wikipedia. The times they are a changing.

Footnote – a day later the date seems to have bounced back to September – don’t know what happened there.  Still not very far off though.
