[newbie] Dynamic IP?

[Jon Doe]

If it wasn't for bad luck, well you know the rest. For 4 months now (the 
entire time I have had roadrunner) I have had the exact same IP number. Now 
RoadRunner decided they wanted to change it I guess. So now my .html files 
all have the wrong links on them. Am I gonna have to edit my html files (for 
apache) everytime they change my IP or is there a way around this?
