DNS Server - HOME

[John Seth]

Never say it's impossible ;)  I do the very thing it sounds like you're 
looking to do, at my own home.  I could be wrong, but... hey, it never 
hurts to find out.

First off, I use Cox Internet, with a Linksys Router (Network Everywhere 
NR041). Not the best of routers I've owned, but it works for the most 
part.  The linksys router handles DHCP for internal IP addresses of 
192.168.1.100 and higher:  Thus allowing me to assign static IP's using 
192.168.1.2 up to 192.168.1.99.  The router itself is 192.168.1.1 and 
it's external IP is grabbed via DHCP from Cox.

The fun part is, I have a fileserver, with a static internal IP of 
192.168.1.2. It will never change, on purpose.  The server has BIND 
installed (also known as "named").  I have it do name-to-ip DNS 
resolving for most of my internal network. That is... 3 desktops, 2 
laptops, a few gaming systems, a windows media computer, and perhaps a 
few other things.  Friends come over, they can hook into my 8 port 
switch, or bring a wireless device and they'll get a dynamic IP. Note 
that, I do prefer my own desktops & laptops to use static IP's in my own 
house... thus, servers are allowed 192.168.1.2 through 192.168.1.10, 
desktops & laptops 192.168.1.11 through 192.168.1.20.  The rest are for 
future use, and I doubt I'll need them. 

After figuring out how I wanted to set them up, and with what IP's, I 
configured BIND.  I won't get into that here, but... I will provide you 
with slightly modified, yet basic BIND/named configurations to download 
and peruse for your use.  They should work to give you a working example 
of what I have here at my home.  By setting up a DNS server on my home 
network, I have use of "int.domain", a fake, and internal domain name 
with hostnames for each IP.  Anything else, the DNS server uses the Cox 
connection to resolve it.  If my DNS server fails, my /etc/resolv.conf 
file also includes Cox's DNS servers as a backup.

If you're interested in how I got it working, I would say check out my 
config's, and look around.  Any questions beyond that, feel free to drop 
me a line back here in the group, or privately.
