Or the contrary, that's standard IP routing, it's just totally useless 
with residential ISPs because most don't allow customers to add route 
entries on their gateway so it's just a flat subnet with no routing 
capability. Business ISPs usually offer the option, it's very common for 
business customers to have a delegated subnet that's properly routable.
