Testing Your Dynamic DNS



Testing Your Dynamic DNS

You can test your dynamic DNS by:

  • Looking at the status page of your DNS provider and making sure the IP address that matches your www site is the same as your router/firewall's public IP address.

  • Using the host www.my-web-site.org command from your Linux command prompt to determine whether you are getting a valid response. If you failed to add your host record, you will get an error message like:

     [root@bigboy tmp]# host www.my-web-site.org

     Server: 127.0.0.1
     Address: 127.0.0.1#53

     ** server can't find www.my-web-site.org: NXDOMAIN

This error could be because your domain hasn't propagated fully throughout the Internet. You can test to make sure everything is okay by forcing NS lookup to query the name servers directly. The example below queries the miniDNS name server ns1.minidns.net:

     [root@bigboy tmp]# host www.my-web-site.org ns1.minidns.net
     www.my-web-site.org has address 97.158.253.26
     [root@bigboy tmp]#
