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?
