I too agree the v4/v6 stuff is pointless and slightly annoying so I have been using same name with A/AAAA records. -----Original Message----- From: Landon Stewart [mailto:lstewart@superb.net] Sent: Tuesday, August 09, 2011 6:16 PM To: nanog@nanog.org Subject: Re: v4/v6 dns thoughts?

My PTRs are all to the same host name. In any context where the protocol actually matters, you should have other ways to detect it.
I also don't recommend doing the foo.v4/foo.v6 thing in your forwards. There's really no advantage to do it. Most tools either have separate IPv4/IPv6 variants or have command-line switches for address-family control if you care.
I agree that using the v4 or v6 tag in forward or reverse is pointless. One can tell it is v4 or v6 by the result of the lookup and the hostnames don't change just because they are accessible via IPv6. If a hostname is directly related to the fact that its IPv6 by all means put it in there though. -- Landon Stewart <LStewart@SUPERB.NET> SuperbHosting.Net by Superb Internet Corp.
