[ILUG] lightweight dns "server" for leaf node?

You might want to read the article about[1] this in the January 2010
edition of _Linux Gazette_ (issue #170), due out tomorrow morning.

Meanwhile:

o Unbound
o PowerDNS Recursor
o MaraDNS's recursive DNS module
o dnscache from whatever is your favourite maintained update
  of djbdns

[1] Well, two articles, actually.  The second explains about different
type of nameserver functionality.  And there's a third that explains
why, no, you should not favour Google Public DNS over a local recursive
nameserver.

Your aDSL modem/NAT thingy, if it's typical, sports a copy of Dnsmasq,
which is only a forwarder.
