Hide IP in FreePBX GUI

Hi,

Could someone point me in the right direction to replace the IP address in the GUI (Freepbx 2.9.0.7 on xxx.xxx.xxx.xxx) with the hostname of the machine. I have done it in the past but for the life in me i cant remember how i did it!

Thanks

Edit: fixed now. Created subdomain and updated cname to point to the asterisk server. Knew it was simple!
