Managing DNS entries

Managing DNS is super easy for the System Administrators. Our primary DNS entry for web portals of institutes is iiits.in. For example cosmos.iiits.in , myspace.iiits.in , studyspace.iiits.in

Steps to follow

  • Log In to DNS Server. IP address of DNS server at time of writing documentation is 10.0.1.2. Server can be logged in by doing SSH to primary server sitting at 10.0.1.29 and then opening the appropriate container.
  • Open the iiits.in.forward file located at /var/named/iiits.in.forward using some editor.
  • You will find many DNS entries already present out there in the file. Entry will be in the following format [secondary-domain-name] [IN] [record-type] [IP-address].
  • Let’s say you want to add test.iiits.in mapping to IP 10.0.3.33. Then the corresponding entry would be test IN A 10.0.3.33.
