At some point the world is going to run out of IP addresses.
At some point the world is going to run out of IP addresses. Depending who you believe, this could happen as soon as next year, or it could take a little longer.There's already a solution, known as IPV6 (the existing one is IPV4). http://en.wikipedia.org/wiki/IPV6 tells you more.
As an e107 user, you're unlikely to see much difference, except that IP addresses won't always be in the familiar 192.168.54.34 format - they'll be much longer! In the worst case they could look like this:
but can typically be shortened a bit:
An address of the form ::ffff:0c22:384e is an IPV4 address mapped to IPV6 notation.
The most obvious effect of this on users is that IP addresses are going to be much longer than previously, which could mess up display (and, initially, maybe cause confusion). On 0.7 many of the storage spaces aren't big enough to hold a full IPV6 address, which could lead to partial addresses being stored.
0.8 is, of course, IPV6 ready - all core (and core plugin) database fields have been sized to hold a complete IPV6 address.
