NimbostratusGTM/DNS - How to delegate just the main domain to GTM
Here is the issue I have with DNS/GTM. We have our own DNS servers that run the main domain i.e. test.com. Specific subdomains are delegated to the GTM's such as marek.test.com. This works great.
...
GSLB for top level domains can not be done through delegation (cname is not an option) You have to be in line. YOu need to create a delegated subdomain from your ISP to the GTM , meaning the CNAME will point to a NS which is the GTM that is the NS for that domain e.g.
Alternatively without delegation you need to be the Authoritative of the entire domain. you can host the Zone file on the GTM , make it the Auth server and add the DTM Wide-IP as the records you wish to provide to GSLB
