Thank you for your help!!
Cox provides the public / routable IP which is set on my router /
modem.
I have a web server that servers several websites. I use NAT for port
forwarding to that one box.
Without a DNS server, either local or external, how will Apache know
which site to server up? If I put the IP in my browser I get the
default "website" which is no website at all - it is the default welcome
page.
