I was told that there is a new file  /etc/inet/ipnodes thatis honored 
under Solaris 10. Unfortunately changing this file did not solve my 
problem. I finally made it, that "ifconfig -A" and "netstat -rn" 
returned the expected results (even) after a reboot. However, the 
interface did not work. I neither could ping out nor in. The interface 
simply was dead.

I finally replaced the switch - which alone did not do the trick - and 
then did sys-unconfig and started from scratch. This got me going!!! 
There must be even more files that are honored. I learned from this 
that changing ipaddresses under Solaris 10 is no easy task and does not 
work very well (at least for me).

Thanks for all your responses!

Regards,

   Andreas
