According to some sources allocated IP addresses under the current Numbering scheme will be in short supply in a few years (c2010 or 2011)
You see the website page name but they have been allocated a ID random number too for the servers to post it
These range from 0.0.0.0 to 255.255.255.255
giving 4 billion combinations (IPv4)
So What happens...Answer the servers are switched over to a new address protocol and the New numbers will be listed under IPv6
The new numbering system looks like this 0000.0000.0000.0000.0000.0000.0000.0000
And the maths people saying it will come to Get this for a total...340 trillon,trillion trillion
Has better background info on this subject

Now if you have Vista the protocol is already set up...No worries

But XP has it but not switched on
Perhaps M$ will switch it on later(in a patch!)

But Lets Jump the Gun and switch it on Now
And you can update your other XP computers too
It will take all of 10 to 15 seconds TOPS to switch it on and resume what you are doing
Open the Control Panel>Network connections
Right click on either of the Local Area Connections > click Properties

On the list the last item is called Internet Prococol (TCP/IP) Yes? Thats the control for web addresses

Transmission Control Protocol/Internet Protocol. The default wide area network protocol that provides that provide communication across diverse Interconnected Networks

Now scroll upwards there is no other item with TCP/IP Listed? If yes it should be ticked
If you see nothing this next bit is faster than sleight of hand
Click the Install button beneath the list then "Protocol" on the Next screen Then select the driver called Microsoft TCP/IP version 6 press the OK button finished! Is set up and ready for use!
The Blurb for that Item says simply:
