Solaris 10 ip Address Change reference document 2, solarisip
Refer to: Cannot change IP address of Solaris [TM] 10 host (Doc ID 1007942.1). This article will not be translated.Symptoms
Changing the IP address in/etc/hosts (linked to/etc/inet/hosts) and rebooting does not change the primary interface's address.
Resolution
Change the entry for the host in/etc/inet/ipnodes.
Additional Information
Prior to Solaris [TM] 10, IPv6 was not enabled by default. So there wocould only be entries in/etc/inet/ipnodes for any systems you may be want to use IPv6.
The host itself is only (by default) in /etc/inet/hosts. Therefore changes to /etc/inet/hosts would be effective on the next reboot.Starting in Solaris 10, the host has entries in both /etc/inet/hosts and /etc/inet/ipnodes. Both files should be kept in sync; however, if they do not match, ipnodes has precedence. If ipnodes has the old IP address, changes in /etc/inet/hosts will appear not to have any effect.
