Cnames and what's allowed

[bettyb]

I am still learning all about zone files and would like to have a link to anywhere there is a good discussion on this.

Currently, my question is with CName.

For instance, let's say we own: test.com

So my Cname test.com points to

http://www.test.com

I can then set up a

cname new.test.com pointing to

http://www.abc.com

Now I have someone here requesting I set up:

new.tested.com pointing to

http://www.abc.com

BUT we don't own tested.com - - just test.com. So would I be allowed to do that? I thought the answer was no.

Any advice is appreciated. thank you

If you setup tested.com it simply won't work because no one would ask your name server for the information. The root servers hand out authorative nameserver for domains but don't know yours.

The alias (cname) you want to set up in tested.com is not a domain that your name server is authoritative. When you reload you name server it will drop the entry and not answer queries for the alias.
