It would seem that the current stack of IP numbers, called IPv4, will probably run out in about 3 years time.
IPv6, which solves the problem for the foreseeable future, has been ready to roll out for 10 years. Servers and routers are already set up to use IPv6, but no ISP has implemented it because no one has asked for it.
Anyone fancy asking Plus?

You can offer IPV6 and IPV4 - many devices and OS's simply aren't set up to deal with it. I haven't a clue whether my router supports it.
Every IPV4 address can br specified as a IPV6 address, but not conversly.
Note that whilst IPV4 addresses can be written as a "dotted quad", if IPV6 address's were written in the same style (which they aren't), then they would require a string of 16 numbers.
IPV4 addresses are 4 bytes; IPV6 are 16 bytes.
"IPv6 addresses are normally written as eight groups of four hexadecimal digits. For example, 2001:0db8:85a3:08d3:1319:8a2e:0370:7334 is a valid IPv6 address." [see Wikipedia].

I'm sure the goverments would love IP6 though so they can track what we get up to in realtime

Quote from: shellsong I am given to understand that there are more possible IPV6 addresses than atoms in the universe ...
There are thought to be about 10^80 atoms in the universe.
There are only about 3 X 10^38 IPV6 addresses.
So they are short by a factor of "quite a bit"

Sod it...I tried not to say anything and knock this thread off topic but.........
Considering the universe is infinite the error is quite a bit larger don't you think?
Who actually controls the issuing of IP adresses worldwide?
The answer is here.

There are LOTS of unused IPV4 addresses, due to huge blocks of class A space having been handed out in the early days of the Internet. For instance, HP owns TWO class A networks, giving it roughly 1/128 of all the IPV4 addresses in the world. MIT, Apple, IBM, GE, and other companies also own class A subnets. There is no justification for these companies owning such large subnets (there are only 125 of these, exluding 0,10, and 127), and releasing these could prolong the IPV4 namespace for many more years.
Just my 1p (2c approx).

Asked them a couple of years back, I think.
A chap called Jeff Huston has been mapping the use of IPv4 address space for quite a time now - his website is...
http://www.potaroo.net/
In a recent article he does point out that the financial drivers probably don't currently stack up for ISPs.
Also as far as I'm aware my router doesn't 'do' IPv6, and there's going to be some old workhorses in the personal firewall arena that don't do it either.
Like someone else said, some class A blocks ( the number of which seems to have grown since the last time I biothered looking) have been returned to IANA. The USA DoD still seems to have a surfeit of class A's (IMO) since they don't advertise all their IPv4 address space (as do some other entities with class A networks).
