BIND is the reference implementation of the RFC's covering DNS. It
contains both a DNS service and a DNS client. The DNS client is the part
that "resolves" queries into answers, resolver part.
Resolvers and resolver routines are also usually present in an OS with a
tcp/ip stack. These resolvers, in general, will not interatively follow
"referrals" ("best" NS's known by the answering DNS + their ip addresses
aka "glue") returned by DNS to get an "answer", but send recursive queires
that are asking the queried DNS to navigate the namespace to get the "answer".
eg, a Windows resolver sends recursive queries, expecting an answer. If it
is given a referral, it won't re-iterate the query to the referred-to DNS
to find the answer.
