Hi Steve,

sorry, i've not followed the whole thread - and dhcp is sometimes a bit tricky.
Just some notes when you use the "dig" tool from ISC - which is very powerful,
but also has lots of options.

In your /etc/resolv.conf beside others you use:
search hh3.site dragonet.es

By default, dig does *not* use that search line from /etc/resolv.conf, but you can
tell it to do so (when you want to only use the hostname for the query):

dig +search lubuntu-laptop

Btw - users sometimes think "more is better" and often place both
domain my.domain.org
search my.domain.org
into /etc/resolv.conf
but "man resolv.conf" clearly states:
 "The  domain  and search keywords are mutually exclusive.
  If more than one instance of these keywords is present, the last instance wins."

Cheers, Günter
