Hello all, I was trying to follow the thread on the NXDOMAIN and got lost. :) I
have a question about using forwarders. If the DNS that is using forwarders
receives a query for a zone it's not authoritative for even if it's in the same
network, does it go to the forwarders for zone information?
If the records which are being requested are in the DNS server's cache
then it may return the records directly from cache (depends on your
configuration). If the record isn't in the cache it will attempt to
fetch it and return it to the client, it will then be placed in the
cache so subsequent
Hi Mike,
To keep my answer simple, if BIND is set up to allow recursion, and gets
a recursive query for a zone it's not authoritative for, it'll:
1) Answer from cache
2) pass the query off to the configured forwarders
3) If the forwarders are unavailable, follow delegation itself to answer
The point of being authoritative is to have a full copy of the zone, so
that one is basically autonomous, not dependent on anyone else to
resolve names in the zone. In BIND terms, that means type master or
type slave. That's why authoritative zones override forwarding,
since forwarding is a
