FYI... I originally posted to this list by mistake, but I'll follow up
because a number of people did send private emails offering help and
suggestions (thanks).

I think you might be referring to a situation where host relies on
another (router or default gateway) to do proxy arp in order to reach
other hosts on other networks. A host route, where the network mask
is 255.255.255.255 is a legitimate entry in a routing table most
typically used for a point-to-point link, loopback interface or
other directly connected host.

Literally seconds after my post hit the list, Casper Dik (of course :-)
sent me the info I needed. I needed to enter the IP address in CIDR
notiation (e.g. 192.0.2.254/32) in the /etc/hostname.lo0:1 file. I
also did the same for the dmfe0 interface, plus removed network and
associate network mask info from the /etc/inet/netmasks file. All
good now.
