[lug] host lookups

[D. Stimits]

First, some notes...
(my nslookups use idcomm.com's name server)

nslookup finds this (interesting it is routable)

The 3 above are not found by nslookup.

My own box fails to find host for itself. This is probably the way it
should be. Maybe someone else can answer this...unless a non-routable
internal network has its own nameserver running for the
internal/unofficial ip's, then nameserver lookup will always go to the
outside world, and thus fail?

Do you run your own nameserver? I suspect you can run ping juice or any
other name, and get an instant ping success. Probably it is only DNS
lookup that is failing via the host command.
