In a distributed hash table (DHT), a participating node has a routing cache associating nodes in the DHT with their respective network addresses. Messages can be routed with the routing table using prefix-matching or numerical-closeness without requiring rigid structuring of the node's cache. Entries in the cache may be replaced using routing information obtained from en route messages. Entries in the routing cache may be replaced without regard for the nodeIDs in or entering the routing cache, and/or without structuring the routing cache according to the nodeIDs placed therein. Cache entries may be replaced randomly.
