When setting up GTM with an existing DNS infrastructure, the location of the DNS servers is not relevant (on prem, off prem, cloud). What is relevant is the proper configuration of the Network Solutions DNS to reflect the existence of your GTM infrastructure. There are 4 basic steps that need to be considered in the overarching setup:
- Create a sub domain on your existing DNS setup (e.g. gtm.domain.com)
- Configure the existing DNS making GTM server(s) authoritative over the new sub domain
- Any DNS resource managed by GTM will be declared by CNAME (name.domain.com in CNAME name.gtm.domain.com)
- Configure a wide ip in GTM (name.gtm.domain.com) with the appropriate pools, load balancing methods, etc. to return responses that reflect the organization’s requirements

So if the current site is , to accomplish this without changing the name of the site and cert on the site to , I'd just need to set example.com to authoritative on GTM and configure the current DNS to point towards GTM as the authoritative source?
