  • make sure that in the DNS server hosting the xyz zone has a delegation record for sub.xyz containing the NS records pointing to the DNS servers hosting sub.xyz.com.

    The problem appears to be that your DNS servers in the xyz.com domain do not have any information about the sub.xyz.com zone.

  • Your DNS servers hosting that domain are not configured with static IP addresses?  If not, how do you plan to maintain the name resolution processes?  A change in IP on a DNs server would cause issues for name resolution.

  • What I forgot to mention is that sub.xyz.com does not have a STATIC ip address.

  • I do not have a dns server at sub.xyz.com.  I just use sub.xyz.com to access a remote location. I have that subnet setup with freedns and they change the ip address for sub.xyz.com whenever it changes automatically.

    All I am trying to get is all  the computers connected to XYZ.com domain to not look to XYZ.coms DNS when they search for sub.xyz.com.

  • Then create a zone for sub.xyz.com on your DNS server(s).  Since you are working with your friends, you can establish a process that they can notify you when new records need to be added to that zone, or changes to any existing record.  Since you will be hosting the sub.xyz.com zone, your DNS will be authoritative for that zone, from your clients perspective.  Your DNS will not go outside of the box to resolve any hosts in that zone.

    Did you even look at freedns? It is not my friends! It is a service similar to dynds that allows me to create subdomains for any domain you own. Then you can add that subdomain address into a router.  Then when the ISP issues out a new ip address freedns updates the ip for that location. Make since?
