The name server uses a random, non-privileged port for sending queries
to other name servers. This port number is reported in the logs when
the name server starts:
	Forwarding source address is [0.0.0.0].nnnnn
where nnnnn is the port number it uses.

This port is not used for receiving queries. [How could another name
server know which (random) port the name server was using today?] If a
query is sent to this port, a waring is generated in the logs.

The query-source clause can be used to tell the name server which
address and/or port number should be used for making queries to other
name servers.
