I would like to get a server up and running I have been trying to install one with Red Hat Linux but before I can start I need a few things. That is why I'm posting.

I would like to know if any one can tell me how to go about getting a 'Nameserver IP', 'Netmask' and a 'Default Gateway'.

I already have a domain name how do I set up the IP Address if it is currently hosted on another server like Interland.net?

Any help would be greatly appreciated.
Furthermore if you can also provide me with some information as to where I can pick up MySQL and Microsoft Access
