Hi everyone,
I am trying to configure my DNS. Here is what I am trying to do.
I am trying to alias www.abc.com to www.cs.abc.com
The problem is arising as cs.abc.com is a delegated sub-domain to a
different name server.
When I request for www.abc.com and see the DNS queries on a sniffer trace,
here is what I observe.
The abc.com nameserver returns a Answer Record, saying that www.abc.com is
www.cs.abc.com. and gives the IP address of ns.cs.abc.com, which is the
nameserver of the delegated sub-domain. But the client name server doesnt
send a query to ns.cs.abc.com to figure out the IP address of
www.cs.abc.com.
Can anyone please point out if this is a problem with the client name server
or with the name server configuration on any of the two nameserver
ns.abc.com, ns.cs.abc.com
Configuration on ns.abc.com (name server for abc.com)
www 1D IN CNAME www.cs
cs 1D IN NS ns.cs
ns.cs 1D IN A 1.2.3.4
Configuration on ns.cs.abc.com (name server for the sub-domain cs.abc.com)
www 1D IN A 2.3.4.5
ns 1D IN A 1.2.3.4
thanks for any pointers about issues in the concept, or configuration and
your time,
- Ravi.
