GTM and Delegated Zones

Hello,

 

My first GTM install ! so apologies, I think this might be more of a DNS question but;

 

There is a data centre with apps in it at one of our clients, we are going to take over so there is a migration plan of sorts I'm sure.

 

In the meantime, they are the owners of domain1.com.

 

We are standing up a test server in our data centre and we own domain2.com

 

The URL for their test app that ios going to live in our DC will be app1.domain1.com, only it doesn't live there.

 

If I ask them to create a delegated zone as follows;

 

delegated zone name = global

 

NS gtm1.domain2.com my IP address

 

NS gtm2.domain2.com my IP address

 

A record IP of gtm1.domain2.com

 

A record IP of gtm2.domain2.com

 

app1.domain1.com CNAME app1.global.doamin2.com

 

This doesn't seem to make sense to me, why would I create a delegated zone in one domain and then CNAME it to another domain.

 

How can I get them to query our GTM for the record ?

 

Does any of that even make sense !

 

Cheers,

 

George

    If app1.global.domain2.com is the wideip on the GTM and you add the CNAME per your post then you do not need the delegation.

    Hi Stephen,

     

     

    Happy New Year and all that. Thanks very much for your reply. I figured it out eventually. I had to create a delegated zone on our ISP so the flow was a little like this;

     

     

    app1.originaldomain.com CNAME app1.toourispdomain.com

     

     

    Then on our ISP i got them to create a delegated zone with the GTM as the NS server and on top of that get them to create another CNAME

     

     

    app1.toourispdomain.com CNAME app1.mydelegatedzone.toourispdoamin.com

     

     

    A little messy but it did the trick

     

     

    Thanks again, now watch out for my next GTM question !

     

     

    Cheers,
