PTR records<BR><BR></FONT></DIV>That's an excellent question !
<DIV><BR></DIV>
<DIV>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
away….</DIV>
<DIV><BR></DIV>
<DIV>Anybody else, who's rolling out IPv6 on a large scale, have any comments
?</DIV>

like to question my habits -- the current one: while getting ready

and<BR>not bother to match the forwards (so far, I'm not convinced either
