In the past eight years, I've had no problems getting any of my ISPs to do
this. To forestall the inevitable arguments, I am aware that living in the
Seattle area blesses me with a plethora of cluefull IPS admins who cater to
the geek crowd. However, I know many people around the world who have gotten
their ISPs to implement some sort of forwarding. Having an RFC to wave at
them helps a lot; it assures them this is a standard practice, not some weird
one-off.
I have gotten AT&T to do it properly. In fact, they do it by default.
However, cox.net, for instance, actually has an unwritten policy that
their technicians always quote saying, "we never delegate rDNS because it is
too inefficient". (But Cox will at least change a PTR if you pester them
for a couple of days...) For a typical DSL monopoly, after you explain
what PTR records and rDNS are to the first few tech support tiers over the
course of several hours, mostly on hold, the answer is that their rDNS is
magically provided by some equipment they don't understand, and they don't
know how to change it.
I actually would be quite happy if ISPs provided a web interface
for rDNS instead of delegating (I mean, come on, all the forward DNS providers
have it). But it looks like IPv6 will be the only way this problem will get
resolved.
