Currently, we have the following DNS servers setup for reverse DNS of IPv4 and IPv6 ranges:

rdns0.v4.rdns
rdns1.v4.rdns
rdns2.v4.rdns
rdns0.v6.rdns
rdns1.v6.rdns
rdns2.v6.rdns

Where the v4 servers are used only for reverse DNS zones for IPv4 and the v6 servers are used only for IPv6 reverse DNS zones.

Upon a partly reconstruction of the network, I'm just wondering if there are any advantages to using separate IPv4 and IPv6 DNS servers.

    Is .rdns a real TLD somewhere, or did you just make it up? That said, no, I don't think I've ever seen that sort of v4/v6 separation, nor can I imagine why it would be useful. – grawity Oct 22 '17 at 20:19
  • I removed the last part so it's not an FQDN. – William Edwards Oct 23 '17 at 7:44
