Hello, first: Please excuse, there was transposed digits in my question, I mean RFC 1912. > It might be helpful if you said a bit more about the problem(s) which > encouraged to to ask these questions. I'm a private customer of a not so small DSL Internet Provider in Germany and I use an ADSL2+ internet access product for very small companies. My internet access provider offers an internet access via ADSL with a static IP address. The advertising message, as I signed the agreement with this company, was: "With this internet access you can run your own mail/web servers." ... but without PTR I can not run my own small mail server. Since more than a year I discuss with this company about this topic without any success. The 1st level suppport does not understand, what a PTR is and why I need it (... btw: This company offers customers with this product (like me) an experts hotline ... *no comment*). It was for me impossible to contact a person with expert knowledge behind this 1st level support wall of stupidness. After many, many requests I got answers like this from this company: "If you would pay more per month, you would get a PTR. Your product is for companies with less than 5 members of staff, we don't offer a PTR for this product and we don't offer support for your own mail server. But if you want a PTR, you can order one of our SDSL products." (btw: I never asked for support "how to setup a mail server", because I know enough about this.) You see, there are _only_ commercial interests to avoid a PTR for my static IP address. I checked the IP address range around my own IP address (It is i a x.y.0.0-x.y.89.255 net.). Perhaps 2% of ca. 23.000 IP addresses have a PTR. All internet access products from this company without a static IP address have generic PTR. >> Does or does not RIPE claim the compliance with (basic) RFCs (like RFC >> 1921, 2.1 - I think it is a basic, that every IP must have a correct >> PTR record.) for assigned IP nets? > > To the best of my knowledge, RIPE (and the NCC) have no policy in this > area. It's a pity that RIPE does not expect a good quality of reverse lookups for used public IP addresses. > Note too that RFC1912 is rather old -- the DNS landscape has changed a > lot since it was written -- and only an INFORMATIONAL.

I'm not sure if it's wise to use this RFC as the > foundations of a RIPE policy. However that is something for the WG to > decide. Shure, RFCs are not sacred texts, but for system administrators (like me) RFCs are every time a good source to find answers for common questions (i.e. How is the syntax for an email address? How works IMAP, SMTP, DNS,... protocol? W). >> I hope, I found the correct mailing list for my question. > You have. That's fine. So I hope to find an answer. Must an _public_ IP address have a PTR or not? > PS: Please don't say "IP" when you mean "IP address". I thank you for this hint. Please excuse me, my english is really bad :( Best regards, thomas polnik.
