Changing IP Numbers and DNS Lookup?? HELP?

[John N. Alegre]

Hello List,

Could some kind people help me with an issue.

I am running Fedora-core-3

I am changing my IP and need to install new static IP numbers and DNS name 
lookup numbers.  Can someone point me to a list of all places in all files 
where edits to either IP numbers or DNS lookup numbers need to be changed to 
accomplish this?   Can this be done all at once using some GUI tool?

Thank you for all comments.

Peace
john
