Everytime you reboot your Sun Solaris Server, you may find that one or more of your Network Interfaces may not come online.
If you did a “netstat -r”
sunsolaris# netstat -r
Routing Table: IPv4
Destination Gateway Flags Ref Use Interface

BASE-ADDRESS.MCAST.NET solaris10 U 1 0 hme0
default 192.168.0.1 UG 1 0 hme0
localhost localhost UH 1 61 lo0
You may not find that the network for the Network interface not found in there (192.168.0.0 here) and as you would expect adding the netmask manually fixes the problem.
sunsolaris# ifconfig hme0 255.255.0.0
