When changing the IP address on a Solaris 10 box edit the hostname and IP address settings in the following files (if present):
- /etc/hosts
- /etc/defaultdomain
- /etc/defaultrouter
- /etc/hostname.[interface]
- /etc/inet/hosts
- /etc/inet/netmasks
- /etc/inet/ipnodes
- /etc/nodename
After making changes to these files restart networking with:
svcadm restart network/physical
