Hi Robert, On Mon, Feb 27, 2012 at 10:35:26AM +0000, Robert Gauld wrote: You can directly set IPv4 reverse DNS from: https://panel.bitfolk.com/dns/ The technique for doing reverse DNS for less than an IPv4 /24 is detailed in RFC2317. You can also do this from the panel link above if you like. Say for example you have IP address 85.119.82.5. If you tell panel to delegate this to a.dns.example.com and b.dns.example.com then you'd need to create a zone called 5-32.82.119.85.in-addr.arpa. Inside that zone you would put the usual SOA and NS records, plus a PTR record for "5": $TTL 86400 @ SOA a.dns.example.com. hostmaster.example.com. ( 2012022701 ; Serial 1800 ; refresh (30m) 900 ; retrry (15m) 1209600 ; expire (1w) 3600 ; minimum (1h) NS a.dns.example.com. NS b.dns.example.com. 5 PTR whatever.your.host.example.com. You then tell panel to delegate reverse DNS for this IP address to "a.dns.example.com,b.dns.example.com". However, you would have to question what the point of doing all that is, when you can just put "whatever.your.host.example.com" into the panel and have it updated in the zone file on BitFolk's side.
