On our network(which isn't docsis, granted) we use PPPoE for all static IP addresses, because it allows /32 ip address allocations for all home CPE routers, upstream, the routers handle routing via ospf to change the path of where that /32 public IP goes. It allows "zero touch" moving of a customer from one PoP to another.
