Changing IP address

The following steps may be used to change the IP address of a Solaris system.

• Change the host's IP in /etc/hosts for the change to take effect after reboot. If you are using Solaris 10, you must also change the host's IP in /etc/inet/ipnodes for the change to take effect after reboot.
•  Run ifconfig interface ip_address netmask broadcast_address for the IP address change to take effect immediately. The netmask and broadcast_address should be specified if you are using variable length subnet masks (VLSM), but may be omitted otherwise.
• If you are using variable length subnet masks (VLSM), add the host's network number and subnet mask to /etc/netmasks.

If the new IP address places the system on a different network:

• Place the host's new default gateway in /etc/defaultrouter
• Run route add default new_gateway for the new default gateway to take effect immediately.
• Run route delete default old_gateway to delete the old default gateway from the routing table.
