"Thank you for your help!!"
No worries, mate. If I'm actually providing any help :) you're quite
welcome.
It sounds like to me you're wanting to use name-based virtual hosts on
Apache. Like thus:
http://httpd.apache.org/docs/2.4/vhosts/name-based.html
If you will have one public IP address for your multiple domains (aka, web
sites), then you will need an entry in an external DNS hoster for each.
Each domain DNS record will point to the same public IP address (your single
web server). And then it will be up to your Apache server to see
www.wheresmycar.net,
www.dogsmakingfaces.com, and
www.localbeerspecials.com
serve up the appropriate web site. (Note: I'm just guessing that those are
the three web sites you're using; don't know for sure.)
Your web server's non-routable internal IP address shouldn't really ever
come into play during normal usage scenarios. Sure, if you enter the IP
locally on your system you'll get the default page, but that's not really
what external users will ever do. Once you have external DNS host records
set up for each domain, you should be able to test the name-based Apache
functionality. Or, if you want to do that locally before advertising
external DNS addresses you should be able to make some temporary /etc/hosts
entries on your web server which all point to its non-routable IP, just as a
test.
Cheers.

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.

I'm not sure that's a valid assumption, regarding needing a DNS server even
with that functionality. Maybe it is in your specific use, but it doesn't
strike me as a guaranteed necessity.
The learning aspect of it, however, is something I can't debate. If that's
part of your goals, then by all means run wild with it. :)
Cheers.

I assume I need a DNS server since the box is a web server and will be
hosting a couple websites and there will be email as well. And part of the
reason I am doing this is to learn.

From the scenario you describe, no, I don't see that creating your own
reverse lookup zone would be necessary.
Your web server has no other internal systems in your environment to look
up. And for external reverse lookups using the public information (from
Cox, Google, OpenDNS, or whatever your preference) should be fine. I
wouldn't create something that would just require extra
management/maintenance when there's no real use case for it.
(Actually, for just a single box that is only accepting NATed web traffic,
I'm not even sure I understand the need for a forward lookup zone on your
server. Is there some reason that its client DNS configuration can't just
point to your preferred DNS provider? Do you really need a DNS server
functioning on the box?)
Cheers.

Thanks Rusty.
It is one box. It is on a non-routable IP. I use NAT for ports 80, 443,
53... etc.
So are you saying I need to make a reverse lookup for the non-routable IP?
Thanks!!
Keith

Hi, Keith.
Will your environment be needing to do internal lookups based upon IP? For
instance, are you using a non-routable set of IP addresses (e.g., 10.x.x.x,
192.168.x.x) for your environment behind NAT, and will those systems need to
perform name resolution of each other based upon IP? If so, yes, you'll
want to have your own internal reverse lookup zone because obviously Cox (or
any other public DNS provider) will not have that information.
If you really don't need any internal reverse name resolution, then there
may be no need to create a zone. For instance, there isn't an "environment"
of servers you have, it's just this single web server. And the web server
doesn't have any internal network it sits on, it's just got a public,
routable IP address.
Cheers.

Hi,
I'm configuring Bind9 on my web server connected to Cox. Cox configures the
IP reverse lookup.
Do I still need to create a reverse zone file?
The reverse zone file is to lookup the host by IP correct?
Thank you for your help!!
