«RFC 4033: DNS Security Introduction and Requirements». RFC. Internet Society, 3-2005, pàg. 11. «Stub resolvers, by definition, are minimal DNS resolvers that use recursive query mode to offload most of the work of DNS resolution to a recursive name server.»
An earlier definition was given in an earlier RFC:
Robert Braden «RFC 1123 - Requirements for Internet Hosts -- Application and Support». RFC. IETF (Internet Engineering Task Force), 10-1989, pàg. 74. «A "stub resolver" relies on the services of a recursive name server [...]»
«DNS Security Extensions (DNSSEC)». Microsoft, 21-10-2009. «The DNS client in Windows Server 2008 R2 and Windows® 7 is a non-validating security-aware stub resolver.»
