Abstract
Due to the limited number of available IP addresses most
computers on the Internet use dynamic IP addresses which
causes problems for applications that have to maintain rout-
ing tables, for example, peer-to-peer systems. To overcome
this we propose unique peer identifiers in the routing tables
and apply the peer-to-peer system itself to maintain consis-
tent id-to-IP mappings to be used in the routing process.
While this may sound like a recursive hen-egg problem we
show that it is in fact possible to devise such a mapping
service for realistic scenarios. Our approach is completely
decentralized, self-maintaining, and light-weight. It takes
into account security to provide sufficient security guaran-
