Hi list, I first apologise because this is really off topic, but I would really appreciate your opinion on this.
I have had a very hard time configuring a DNS server to answer reverse dns queries, and I would like to have your opinion on my provider behaviour. We have 3 classless subnets and asked the provider to delegate reverse dns. They configured their server and emailed me all was fine but i it didn't work for one subnet, so I mailed back and they assure their side was all perfectly configured. I finally find out (spending lot of time and thanks to www.dnsstuff.com) that they configured 2 zones like 128/27.x.x.x.in-addr.arpa and one as 128-27.x.x.x.in-addr.arpa, so my server was not able to answer queries because I had all zones 128/27.x.x.x.in-addr.arpa. As said before it is my first time configuring Bind and I am sure the more experienced would have notice and solved it quite soon, but still I wonder why to use different convention (without telling us) and even if this is correct (red the http://rfc.net/rfc2317.html and they always use "/" not "-" ). Hope I won't be banned from the list for this email......
Thanks for your time reading this
Simone
