    Accepted Solution

    From the Bind9 FAQ at:

    " Why is named listening on UDP port other than 53?

    Named uses a system selected port to make queries of other nameservers. This behaviour can be overridden by using query-source to lock down the port and/or address. See also notify-source and transfer-source. "
