GTM name resolve for sub-domains from NS

I have external Linux DNS server for my domain.com.

 

Now i Created Cname in linux server

 

. IN CNAME

 

delegate authority for the wip.domain.com

 

wip IN NS gtm1.domain.com. IN NS gtm2.domain.com.

 

gtm1.domain.com. IN A 192.168.101.254 gtm2.domain.com. IN A 192.168.102.254

 

Now my query is,

 

  • When i request the in internet for , i get the answer from GTM box it is has IP of x.x.x.x and cname for it , i am ok with this

** But When I request for somedomain test.domain.com, what will happen, since linux server dont has the cname for test.domain.com, Should i create CNAME and delegate for all the sundomains?*

    Greetings,

     

    My guess is the cname entry is to delegate only a few specific subdomains to GTM / DNS.

     

    Do you intend to answer many name resolution queries for the domain from the Linux server?

     

    If not, perhaps just skip the cname entry and delegate the entire domain?

     

    If only a few are being delegated to GTM, then just keep using the cname.

     

    Hope this is somewhat helpful, thanks,
