I am using the following commands to get the domain name using the IP address
dig -x IPaddress
But it gives me some host names like ns1 etc. Is there any bash command that can give the actual domain name?
ip url

Using the +short option of dig you can get only the dns name.
dig -x 8.8.8.8 +short | awk -F '.' 'print $2"."$3'
There's probably a nicer way to reassemble it with awk Or just return the DNS Domain.
Have a read through the QUERY OPTIONS in man dig

When I do it I get something like this
dig +short -x $(dig +short example.com)
I get
host-198-51-100-0.as13285.net.
This is not the original domain name, because the domain name system has no easy way to look it up, as the real name is not registered in the database, however the one that was returned was. It would be to expensive to ask every DNS server in the world.
In addition there is a many to one relationship. Each IP can have many domain names (sometimes a domain name has many IP addresses, used for load balancing).

There is no need to ask every DNS server in the world. The domain name system has a way to look it up, and it's not more complicated than a forward lookup. In fact, it's very similar: instead of looking up, say,google-public-dns-b.google.com, the PTR record for the domain name4.4.8.8.in-addr.arpais searched hierarchically starting fromarpa.

@Yes sorry If I suggested that it can not be done, I only mean that It can not be done, if it is not entered into the database. Searching the world is what would be needed to do it in reverse, but we don't have to do this, as sometimes there reverse lookup is added to the database.
