New Simple DNS Plus plug-in "Smart Reverse DNS" released
Thursday, 01 October 2015
With this plug-in, Simple DNS Plus can automatically synthesize reverse DNS records (PTR) for all the IP addresses (IPv4 or IPv6) in a subnet .
This can be used if you manage a large number of IP addresses, and you need to provide generic reverse DNS records for these.
The plug-in will respond with reverse DNS records pointing to a synthesized host name in the format <prefix><ip-address-><suffix>. Dots and colons in IP addresses are replaces with hyphens, and you can choose to either include the full IP address, or just the right part (as per subnet size).
For example with the prefix "webserver-", the suffix ".example.com", and a DNS request for reverse DNS records for IP address 22.214.171.124 (PTR for "126.96.36.199.in-addr.arpa"), a PTR record pointing to "webserver-1-2-3-4.example.com" would be synthesized.
