AT&T calls it "Sticky IP address."  A U-Verse Residential Gateway tends
to get the same IP address from DHCP, for months or years, but its not 
guaranteed.  An subnet may change anytime wihout notice for the convience 
of network engineering, i.e. splitting on a new DSLAM slot, moving 
equipment in CO's, replacing the RG hardware, DHCP server changes, etc.

If a cusomer wants assurance and notification about future IP address
changes affecting their IP address assignment, they will need to pay for 
U-Verse "Static IP address" service.
