1. Is there any point to full host names in /etc/hosts ?

This is the situation: a friend and I both use a broadband router with a few
machines behind them, at our respective homes. We each picked a name for our
'domain'. His is fictional. Mine also exists on the net, but with only the
www and ftp of rikishi42.net defined in the DNS, not my home machines.

He's added 2 of my PC's in the /etc/hosts of his laptop, for use when he
visits and connects it to my LAN.

This would be a sample from that file:

# Home net
192.168.108.101   desktop.myDomain    desktop
192.168.108.124   laptop.myDomain     laptop
192.168.108.101   server.myDomain     server
#Rikishi's net
192.168.8.142   gramps.rikishi42.net  gramps
192.168.8.181   pigmy.rikishi42.net   pigmy

We've allways used this, works just fine.
When connectiong to my machines, he's allways used the short (host only)
name. Last time, he accidentally tried with the full name. It failed.

My guess is that, upon finding that rikishi42.net exists, there is an
attempt to get the address from the DNS, skipping hosts all together.

But do I presume correctly, or is there more to it?
