I would like to know who's DNS Server will have the DNS query to GTM that acting as subdomain.
External DNS: company.com (PUBLIC)
www.company.com IN CNAME www.wip.company.com
wip IN NS gtm.domain.com
gtm.domain.com IN A
As a client, i'm using 22.214.171.124 as a DNS Server. When I performed nslookup to www.company.com. I want to know who's DNS server is the one sending DNS query to GTM, is it the 126.96.36.199(Client DNS) or the External DNS (company.com)?
The queries will come from the Client DNS server. Once the query reaches the CNAME record on the External DNS server, the Client DNS will attempt to restart the DNS query process but instead it will search for the domain name listed in the CNAME record.
Thank you Rico!
