You don't say if your DHCP IP is a private LAN IP or a public IP.

If the IP is public and you don't require direct access to this IP from the 
internet, put a router in place between your modem and the server and give 
your server a static private IP.

If you do need a public IP on your server, ask your provider for a static 
IP instead of a DHCP one.
