My ISP provided me with a static IP, so I think that the first
solution seems better suited to my experience level and my
relationship with the ISP. Most of what you said was very foreign to
me, so I feel that I will be learning a lot this week.

I understand that this is not automatic? Will I need to write a bash
script? I know a little php, so I could learn a little bash. What file
should I parse for this information? Or am I stumbling in the
competely wrong direction?

So I should write to the file that contains the TCP/IP settings? Er,
which file is that?
