== Forward zones ==

* When a forward zone is configured, BIND sends a recursive query to the forwarders and waits for an answer. If the forwarder does not allow recursion, and it is needed to resolve the query, the query will fail.
* With a forward zone, the forwarder "performs the work" when resolving the query.

== Stub zones ==

* When a stub zone is used, BIND sends an iterative (non-recursive) query to one of the name servers in the stub zone. BIND will continue to send iterative queries to resolve the query.
* With a stub zone, the BIND server "performs the work" when resolving the query.
* BIND uses both UDP 53 and TCP 53 when populating a stub zone, even if the master name server allows [http://en.wikipedia.org/wiki/EDNS EDNS]. BIND uses UDP 53 when querying the SOA record for the zone, and TCP 53 when transferring the NS records and A glue records. I find this surprising as IXFR and AXFR aren't involved.
