Funny you bring this up...
We're in the middle of rolling out IPV6 as well and was pondering the
same question...
Have not come to any conclusions yet but very interested in hearing from

	That's an excellent question ! 

	I seem to recall a heated debate at the RIPE meeting in Rome
back in November.     It would seem that most people wish PTR was never
invented and it causes more grief than its worth.    A few folks seemed
to be resigned to having to do PTR for MTAs and other services that have
built-in requirements but most would like to see the entire concept go

	Anybody else, who's rolling out IPv6 on a large scale, have any
comments ?
