The point he was trying to make is that there is no standard for what those "appropriately named PTRs" should look like. He has forward/reverse that is perfectly ok according to standard (forward/reverse matches) and if he had a automatic dictionary for naming those IPs instead of putting the IPs there, things would be different.

If people want to make standards on how to put information into DNS for RBL use, they should take it to the IETF and make a standard out of it, not just ad-hoc

I did.. a number of people went out of their way to bury it. One of who would do anything to bury anything SORBS does (I think we all know who that was.)

create something of their own and expect everybody else to conform. If there is an "industry standard" (which the replies here seem to indicate), that should be written down and standardized by the people who actually make money out of it, in this case Trend Micro. This would remove the problem of having to maintain tens or hundred points of contacts for "what is dynamic dialup space" which is the problem right now as there are a lot of RBLs to deal with.

Creating a standard on what to put in WHOIS/DNS for dynamic/static/infrastructure would make a lot of sense, seems nobody is doing it though.


100% with you!!!!

...and if people used "static" and "dynamic" keywords in DNS as I suggested in my previously mentioned draft, there would be *NO NEED* for DUL/DUHL/PBL lists at all because people could create a very simple set of patterns to match and therefore the RBLs would be unneccessary.. (and it would save me about 10 hours a day, every day of the week, every week of the year!) Currently I have a few 100 patterns and I know another on this list has more like the region of 10k patterns to do what in reality one should be able to do in 2 (10 at the most!). At 10k patterns it becomes a lot cheaper to use DUL/DUHL/DYNABLOCK to block dynamics, does anyone wonder why people do?
