Re: DNS/Domain questions
First, off, my guess is that you are using NAT. That is, you have 1 public
IP address and several machines at home which share that IP using NAT
(provided by a SOHO dsl/cable router box).
In this case your home machines will never be visible to the public world.
You don't need to provide DNS for them. All you need is one domain name
(myname.com) which points to your public IP. You are already getting that
service from your registrar. Your machines behind the firewall don't need
DNS names because they are invisible to the real world.
If you want to have your private machines do things like www service, you'll
need something like port forwarding, so that e.g. myname.com:80 gets
forwarded to e.g. mynatip1:80. A different port can be forwarded to a
different machine, e.g. myname.com:25 -> mynatip2:25. The linux kernel
handles this stuff, through ipchains I think, but your SOHO box probably has
it built in.
Anyway, if this is your situation then the one thing you don't need, and
can't use, is DNS.
