The DHCP protocol is supposed to allow lease renewal throughout the 
lease period, and clients are normally expected to renew their lease 
halfway through the lease period. So a continuously-connected system 
should retain the same IP address.

If ISPs are *forcing* lease renewal they are perverting DHCP. Network 
service should be continuous as long as a system remains continuously 
connected.
