That's just not a proper DNS setup. It's not really important when it's not a mailserver or doesn't use TLS, but a reverse map should only have _one_ result.
Can you point me to the RFC for this?
I don't believe there is an RFC describing it. From a DNS point of view, having multiple PTR records for one address is perfectly valid, it just doesn't work as expected. The main thing is the client doing the reverse lookup, postfix or a browser for instance. They only use _one_ result, the first one. I have seen this often enough with postfix. http://serverfault.com/questions/618700/why-multiple-ptr-records-in-dns-is-n... (the first two answers). https://en.wikipedia.org/wiki/Reverse_DNS_lookup#Multiple_pointer_records If it were me, I would map 130.57.5.70 to "suse.com", that's all. Or maybe "novell.com". Funny, neither one is in the current list of PTRs :-) best regards Per -- Per Jessen, Zürich (18.4°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: heroes+unsubscribe@opensuse.org To contact the owner, e-mail: heroes+owner@opensuse.org
