This is a standard term in DNS. See p.26 of DNS&BIND, or Section 5.3.1 of
RFC 1034.
A stub resolver is a resolver that relies on use of a DNS server that will
perform recursive queries on its behalf. It has no knowledge of root
servers or the DNS hierarchy -- it just sends queries to a preconfigured
set of servers and expects them to reply with the final answer.
A non-stub resolver will perform iterative queries by itself.
Almost all resolvers are stub resolvers.
