TCP/IP Settings

Changing a Server’s IP Address

Changing a server’s IP address isn’t as simple as changing the TCP/IP settings. Address information is set throughout the system when you set up the server. To make sure that all the necessary changes are made, use the changeip command.

To change a server’s IP address:

1Run the changeip tool:

$ changeip [(directory-)] old-ipnew-ip [old-hostnamenew-hostname]

Parameter

Description

directory

If the server is an Open Directory master or replica, or is connected

 

to a directory system, you must include the path to the directory

 

domain (directory node). For a standalone server, type “-” instead.

 

 

old-ip

The current IP address.

 

 

new-ip

The new IP address.

 

 

old-hostname

(optional) The current DNS host name of the server.

 

 

new-hostname

(optional) The new DNS host name of the server.

 

 

For more information or examples, see the man page.

2Use the networksetup or serversetup command (or the Network pane of System Preferences) to change the server’s IP address in its network settings.

3Restart the server.
