[SOLVED] Linux IP Changing

Hello Again Guys,
I was just inquiring if there is anyway to alter the Linux IP Address yourself?
Or better yet, if there is a way to keep the IP Address as it is.

The reason for this is because my linux ip address changes every 5 minutes and i have to keep changing the IP Address in the main server files.
It is annoying; if there is a way then fantastic, let me know. If there is no way, then i will just have to survive with changing the IP address all the time.

Thanks,

Thank you very much, it was a massive help!
