Ok here is what i need to do - but am completely lost on how to do it

I have a subdomain of one of my website hostings i need to delegate authority to one of our suppliers as they are providing our outbound emails, I havent a clue how to get the subdomain to point to the other server and also propogate.

any ideas?

thanks

Hi,

In order to point your sub-domain to a diffrent server, you need to edit the domain's db file under /var/named/

Edit the file and change the A record of the subdomain to point to the new IP. Like,

from

test IN A YourServerIP
www.test IN A YourServerIP

TO

test IN A NewIP
www.test IN A NewIP

assuming 'test' as your sub-domain. Make sure you restart bind when the changes are done. Restart bind using the command as: /etc/init.d/named restart

With the above settings your sub-domain will entirely work from the new server. If you wish to host the sub-domain from our server and emails from a different one, in that case we will have to create a new zone for the sub-domain. So please raise a ticket with the details like sub-domain name, the new IP and we will do the needful.

Interesting, unfortunately they want full DNS control of the subdomain

This is where my bind knowledge from teh extremely basic course i did at uni is failing me

Hi,

I am afraid but that's not possible. Making changes on the server for emails to work from a different server is easy but a separate DNS control for a sub-domain is not possible.

You can setup a CNAME record for a subdomain which will point to a domain hosted on the external server. any changes you make in A records of that particular remote domains will change A records of the subdomain as well.

This may sound confusing but this is how DNS works

am i correct in thinking this subdomain coudl point to a DNS entry?

we are doing this for domain masking with a supplier off ours.

This is possible only by setting up CNAME records for the subdomains on primary DNS Server. This way the destination server ( where CNAME records are pointed ) will have full control of the subdomain.

This is indeed very interesting.. but a little question is popping up in my mind... Why would any one require full access over a subdomain DNS..?
