Hi!
I have set up a view for one site. It is bound to change answers as
necessary for different IP-ranges. It works as far as I could see.
But with one ip-range there is a problem ...
I can query internal addresses:
!user@kvm2~# host intweb.example.de
!web.example.de has address 192.168.180.46

To answer the original question. There isn't a flag for the query

The zone is badly configured so that all queries end up going to a
dead server after a sucessful query.
nameserver1.gpi-g.com says the NS RRset is just nameserver2.gpi-g.com.
nameserver2.gpi-g.com returns SERVFAIL.
Both nameservers should be listed in the zone rather than just one

No. There are no plans to remove support for stub zones.
Whatever you're trying to accomplish, it's would not appear to be consistent
with the founding RFCs for DNS:

Just delegate the /16's that make up the /10's. I don't understand
why people want to make this more complicated than it needs to be.
Similarly of /17-/23 you just delegate the /24's. Using CNAMES
only make sense for /25-/32.

Hello,
I have a caching nameserver setup it has been working for ages. Today I have a
problem resolving a particular domain and I just cant see why there is a
problem. (BIND 9.5.0-P2)
It appears that ONLY I have a problem resolving this single domain !

lame-ttl is an option in named.conf which defines the number of seconds
to cache lame delegations or lame servers i.e servers which are marked
as authoitative but do not respond as authoritative. Set that option to
0 so that you will never cache a bad delegation.

You could use something much simpler like dnsmasq

Hello,
I have posted a patch at
https://lists.isc.org/pipermail/bind-workers/2011-July/003061.html.
It might be a hack but it does the job and passed some simple tests
that i did to verify the functionality that i wanted.
The patch is against BIND 9.7.1-P2
