There is a new draft published trying to address the routing architecture of Internet http://tools.ietf.org/id/draft-frejborg-hipv4-00.txt
This draft describes a framework how the current IPv4 address structure can be extended towards a similar hierarchical numbering structure as used in the Public Switched Telephone Network and bring hierarchy to the routing architecture of Internet. The framework requires extensions to the existing Domain Name System architecture, the existing IPv4 stack of the end systems (hosts) and to routers in the Internet. The framework can be implemented incrementally to the hosts, databases and routers. The idea is quite simple, it will require changes to all disciplines but from the networking point of view it will not require changes to the current forwarding plane except that a new networking element (LISP Switch Router) is needed at each Autonomous System or at several AS controlled by an ISP. This framework will bring hierarchy to both the IPv4 addressing structure and to the routing architecture of Internet.
