What is status of your dnssec-validation? .hub does not exist in public
dns tree and dnssec has a proof that it does not exist. Any validating
resolver will therefore turn the response to NXDOMAIN. You should use
your own existing domain with a proper delegation instead. Or use just
home.arpa domain, which is reserved for local use of networks. If you
want to keep .hub, you will have to set exception to not validate this
domain on every validating resolver in your network.
# to allow this domain forever, add to named.conf options{}:
validate-except { "hub" };
Cheers,

I'm struggling with subdomain creation, for some reason the delegation
glue records are being ignored - and i was wondering if someone could
help me identify what I've done wrong please. I know i need to setup
another server for the subdomain, but I've been trying to get this
going at work and getting the same issue, so thought to try on my test
bed. Can't even get the NS record returned for the subdomain
Given the domain ".hub" I can verify the domain level NS
# host -t NS hub localhost
> hub name server localhost.
I can create an A record for "salmon.hub." and this resolves as
expected:
# host -t a salmon.hub localhost
> salmon.hub has address 8.8.8.8
I want to delegate to a different domain server the subdomain
"fish.hub" and have created glue records as below in the config
snippet, but get NXDOMAIN for both the A record and the NS record
# host -t a ns1.fish.hub localhost
> Host ns1.fish.hub not found: 3(NXDOMAIN)
# host -t NS fish.hub localhost
> Host fish.hub not found: 3(NXDOMAIN)
Any suggestions gratefully received. Pertinent parts of named.conf
and zone file are shown below, if you need more info please don't
hesitate to ask
thanks in advance!
