On PowerDNS on a Raspberry, I have recursor pointing to Google (8.8.8.8) and only one zone file and it contains:
$ORIGIN abc.co.uk.
$TTL 1h
@ IN SOA ns.abc.co.uk. hostmaster.abc.co.uk. (
1; serial
1d; refresh
2h; retry
4w; expire
1h; minimum time-to-live
)
IN NS ns
IN A 1.2.3.4
www IN CNAME def.com.
ns IN A 192.168.9.100
Querying for abc.co.uk works, but www.abc.co.uk does not return a CNAME of def.com. What could be the cause of the error? The nslookup output is as follows (with annotations):
> set type=any
> abc.co.uk
Server: 192.168.9.100
Address: 192.168.9.100#53
abc.co.uk nameserver = ns.abc.co.uk.
abc.co.uk
origin = ns.abc.co.uk
mail addr = hostmaster.abc.co.uk
serial = 1
refresh = 86400
retry = 7200
expire = 2419200
minimum = 3600
Name: abc.co.uk
Address: 1.2.3.4 // looks ok?
> www.abc.co.uk
Server: 192.168.9.100
Address: 192.168.9.100#53
Non-authoritative answer:
www.abc.co.uk canonical name = abc.co.uk. //!! result from Google?
Authoritative answers can be found from:
If I omit the period after def.com in the CNAME line in the zone file, then the query returns:
> www.abc.co.uk
Server: 192.168.9.100
Address: 192.168.9.100#53
www.abc.co.uk canonical name = def.com.abc.co.uk.
