CumulonimbusHi,
each DNS forwarder hides the source requester.
If :
- the client requests ForwarderA
- ForwarderA requests ForwarderB
- ForwarderB requests root server,then zone servers and sub-zone servers (GTM)
GTM will see ForwarderB as client.
DNS forwarder role is like a proxy, DNS server Role is the server which have the database.
If you create a sub-zone gslb.company.com with GTM as NS records, the request is not done by company.com server, but by the forwarder which receive NS answer.
