Configuring ISP to use on Linux Mandrake 8.1

To the experts:  I am going to be in the process of setting up Mandrake and in the process of installation of the program with an ISP it calls for the IP address of my ISP which is Comcast.  I called Comcast and they said their IP addresses are static meaning they change.  How do I manually enter an IP address for this ISP in the blank white box when it calls for one?   There isn't one listed under Networks in the Control Panel.

Thank you.

Static IP mean FIX IP, not change dynamically like DHCP.

As root, use
netconfig
to config your Linux box's IP.

Thank you wesly:  When you say as root use netconfig do you mean to type the word netconfig in the run command of Windows?  If so, I have done that and it says it is missing.  What would be an IP address I could use?

Thank you.

I believe they don't give you the fix IP unless you pay extra fee for it.
If the IP will change, then you get the IP from DHCP.
Then in "netconfig", simply check "... dhcp..." and reboot.

wesly:  Thank you for your comment.  You mentioned to get the IP from DHCP.  How do I get the IP from DHCP to configure the ISP?  

Thanks

I mean your cable modem might get the different WAN IP address from your ISP.
So your ISP have DHCP server running to DYNAMICALLY assign IP address for your cable modem
or your Mandrake, which connect to cable modem.
