Changing the IP Address of a Server

You can change the IP address of a server using the Network pane of  
System Preferences or the networksetup tool.

When a network address change is detected, no matter how the change  
happened, changeip is invoked. The tool changeip goes through all  
configuration files and places where the Server’s IP address is  
stored, and changes the address to conform to the new address. The  
server’s IP address can be changed without changeip being invoked from  
the command-line.
