'''Key-based routing''' ('''KBR''') is a lookup method used in conjunction with distributed hash tables (DHTs) and certain other overlay networks. While DHTs provide a method to find a host responsible for a certain piece of data, KBR provides a method to find the ''closest'' host for that data, according to some defined metric. This may not necessarily be defined as physical distance, but rather the number of network hops.<ref name="urlP2P Networking and Applications - John Buford, Heather Yu, Eng Keong Lua - Google Książki">{{cite book |url=https://books.google.com/books?id=O9NkAaY9YxMC&q=Key-based+routing+freenet&pg=PA58 |title=P2P Networking and Applications - John Buford, Heather Yu, Eng Keong Lua - Google Książki |isbn=9780080921198 |last1=Buford |first1=John |last2=Yu |first2=Heather |last3=Lua |first3=Eng Keong |date=11 March 2009 |publisher=Morgan Kaufmann }}</ref><ref name="urlDistributed and Cloud Computing: From Parallel Processing to the Internet of ... - Kai Hwang, Jack Dongarra, Geoffrey C.
