Which DNS record should I use to redirect request to sub domain to main domain

domain-name-systemsubdomain

I created a DNS record in co.cc to make it point to x10hosting account. So I have like <mydomain>.co.cc - A - <x10 ip>

Its working properly. Now problem is I have already mentioned name like blog.<mydomain>.co.cc in my previous resumes which I cannot change. So is it possible to redirect sub-domain request to main domain using DNS record.

You can add a CNAME, but it would not suffice.

This way you only tell browsers that the IP of your blog is the same as the one pointed by your domain DNS record:

blog.dom.tld -> dom.tld -> <your.ip>

If your HTTP server does not implements Vhosts (and I suppose it does as you are in a shared server :), you would had done.

As your server is a Vhost, you have to instruct it to properly handle both blog.dom.tld and dom.tld as the same vhost. You can achieve this behavior using ServerAlias apache directive, for example

EDIT:

don't know your host, but from their forum it seems you can login and do it by hand.
