RE: Setting up DNS for virtual domains
IMHO, it's not all that complicated, and I'll try to make it seem simple.
In order for a machine to be a DNS server it just has to be running BIND or
some equivalent (that was easy wasn't it). As long as you have a static
routeable IP address and a name to go with it, you are in business. For the
domains that you need DNS service for, just state that your DNS server is
the DNS server for that domain (okay this is confusing). Perhaps an
example! This information is totally bogus, but it will hopefully clear
You have a machine, we'll call it aardvark.anydomain.com and it has an IP
address of 856.238.968.104 (yes, I know that this cannot possibly be valid,
but I don't have any IP addresses of my own). It's running Bind 8 (because
it's a potato box). I go to whomever I have my domain registered through
(networksolutions.com, directnic.com, domaindiner.com, etc.), and when they
ask for a DNS server, I tell them aardvark.anydomain.com, and I give them
it's address of 856.238.968.104. They will tell the root servers (who
really control all this stuff) that anything you want to know about domain I
just registered (mynewdomain.com) can be found at aardvark.anydomain.com
(856.238.968.104). Everyone on the internet then looks to the poor little
aardvark, and it say that www.mynewdomain.com can be found on
webserver.anydomain.com. If your looking for information on how to setup DNS
service, I think that there are some HOWTO's. IMHO, DNS record writing is
an art, so you probably want to ask whomever is doing your DNS service know
for a template. I'd offer, but I blunder through it everytime I do.
Hope I didn't confuse you anymore,
