Don't forget that by default when you install solaris (v2.8 pre 4/1/2002) and
you use a 10.xx.xx.xx address, the /etc/netmasks file always gets put in with
10.0.0.0 netmask 255.0.0.0. You must manually change this prior to the 4/1/2002
release of solaris 2.8. CIDR (classless inter domain routing) allows the
10.xx.xx.xx network to be sub-divided but solaris still assumes a class A mask.

The network called "arpanet" will be the Class A, network 10 - if you check
your /etc/networks you should find this entry. This begs the question, should
your nodes REALLY be on the Class A, Net 10??? If so, is there a route from
your NetView system to net 10?
If you can ping these nodes, you really shouldn't need to use loadhosts,
neither should you need SNMP on the boxes. What did you do with regard to
DNS?? Discovery issues like this usually come back to either duplicate IP
addresses in the network or broken DNS. Use the "netmon -a 12" command and
look at /usr/OV/log/netmon.trace to see if your nodes are on netmon's ping

I still think these nodes are saying they are in the class A, Net 10. This
node with SNMP on it, check the subnetmask that it is using. Devices without
SNMP usually get the subnetmask correct via ICMP but not always, in my
