Zone delegation to GTM/DNS Question

We have a customer whose DNS zone is hosted at an ISP. Say the zone is Customer.com   The customer has many hosted websites at his own premises and he want to migrate to GTM, but not all websites ...

Second that - I agree with Mohamed this approach worked just fine no issues.

 

  1. Created a zone called ext.customer.com on ISP or your external domain hosting DNS provider.

     

  2. Pointed that to GTM's NS record to GTM IP's.

     

  3. Created wideip on GTM's - abc.ext.customer.com

     

  4. Made a CNAME rec on external abc.customer.com CNAME abc.ext.customer.com

     

The external DNS server would know that ext.customer.com is your GTM via NS rec you created earlier.
