I thought it was wrong because the gateway was the same as my nic address.

There have been times that I have thought that this was a DNS issue, but I don't see how this can be just that, as I cannot ping a known, workable host on the internet.

I cannot even ping the router at 192.168.0.1

The /etc/nsswitch.conf is the stock OI configuration.  I have not changed anything in it.

/etc/resolv.conf was empty.  I put "nameserver 192.168.0.1" in it, did a "svcadm restart network", but it did not seem to change anything with the netstat command.
