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. -----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!!
