      The quick answer is the fact that even though you have a DHCP issued IP address, it is what is called a "sticky" IP address, i.e., when your DHCP lease expires, the DHCP server will renew with your existing IP address. This does NOT mean you will ALWAYS get the same IP, since, as an example, if you turn off your router for any length of time and someone else happens to authenticate with their router, they might be issued the IP that you previously had and then when you turn back on, you will receive a new and different IP address.

      Also dependant on what the DHCP servers have the expiration period set for. Microsoft’s default lease expiration time is 3 days, but this can be changed from 24 hours to 33 years!

      Not that Sky would, but if they set it for 33 years your router would grab the same IP each time it booted up.

      If only eh?
