I read in forums about people that could run their own DNS
server at the same server they had their sites, that's why I
tried.  But I know (and I understand why) that the good
practice is to have two external DNS servers in different
locations.

Stop here, this is my obscure point: how do you get that your
dns be asked?  What do you need?  What must I ask to my isp
(my vps provider in this case) for?  What do you mean by "to be
designated nameserver for the IPs"?

Yes, I release of my mistake.  Just one domain for ip.

This is exactly what a cannot do: to dig/nslookup from
external hosts.

Well, my goal (tell me if it is a fantasy:)) is to be able to
update automatically my registers.  I ignore the features and
flexibility of bind, perhaps I should change the strategy.
Could you give me some clue?  Can I use bind just as slave of
the external name server (being it godaddy's dns or my vps
provider's one)?
