"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.

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. -----Original Message----- From: plug-discuss-bounces@lists.phxlinux.org [mailto:plug-discuss-bounces@lists.phxlinux.org] On Behalf Of Rusty Ramser Sent: Tuesday, October 6, 2015 12:10 To: 'Main PLUG discussion list' Subject: RE: Bind9 / Cox reverse lookup 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. -----Original Message----- From: plug-discuss-bounces@lists.phxlinux.org [mailto:plug-discuss-bounces@lists.phxlinux.org] On Behalf Of Keith Smith Sent: Tuesday, October 6, 2015 12:03 To: Main PLUG discussion list Subject: RE: Bind9 / Cox reverse lookup 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.

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?)

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!!

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. -----Original Message----- From: plug-discuss-bounces@lists.phxlinux.org [mailto:plug-discuss-bounces@lists.phxlinux.org] On Behalf Of Keith Smith Sent: Tuesday, October 6, 2015 10:11 To: Main PLUG discussion list Subject: Bind9 / Cox reverse lookup 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!!
