Don't worry you can do this and you def do not need a admin for it.
Log into your web host manager and click "hostname" under "Networking Setup" just click save if it's already correct. If it's not correct then put the right one there and save.
Then under you "dns settings" menu click:
Add an A Entry for your Hostname
Then restart bind under services.
You may have to go to the file /etc/resolv.conf through ssh with root access.
Then pico resolv.conf
make sure the hostname is there and the it has the correct i.p. next to it.
Then save "control x"
and restart bind: /scripts/restartsrv bind
Always update cpanel after major any server changes like this, even if you just did it.

good luck!
And cpanel is great even if your a advanced admin, saves time, keeps things organized. that's why we are authorized partners with them.
