Title: How Many Net Addresses Do YOU Need?
Post by: dave.m on October 30, 2007, 11:25:20 PM

Mr Vint Cerf, one of the founders of the net is waiting to roll out the new IPv6 system of addresses. He states that it will provide '340, trillion, trillion, trillion addresses.'

In real numbers it is something like this:
340,000,000,000,000,000,000,000,000,000,000,000,000.     ???

Read all about it....:

Should be enough for us for a year or two.  :P

IPv6 is in widespread use in the APNIC (Asia-Pacific) region and has been for years. The reason is simple - ARIN (the USA) and RIPE (Europe) kept something like 80% of IPv4 addresses for themselves.

I used to have a /64 allocation* back when I used AAISP as my ISP. It was quite fun learning about it but there's no resilience in IPv6 backbones across Europe and they are non-existant across the USA. In short it was fun but pointless - the situation is still the same in Europe now. Finding a consumer-level router that understands IPv6 is impossible too :(

*18,446,744,073,709,551,616 addresses :)

PS - Adrian at AAISP said anyone who wanted a /48 for "testing purposes" could have one. A /48 is 1,208,925,819,614,629,174,706,176 addresses :D

I can remember when studing in what was probably 2001/2002 ish time when we did the IPv4 thing and CIDR (couldnt get my head around IPv6)... 
and anyhow there was a panic back then that iirc  IP addresses were predicted to run out by about 2005 unless IPv6 was brought in.
