Ron,
I think most of us agree with you that it's a bad idea.
However I don't think it's InterMapper's role to enforce best
network practices.
I am very concerned that we don't do that. We all use InterMapper in
different ways and for different purposes.
I think the question is at this time does ANYONE other than the
author of the original post desire this? If not then, well, so it goes, I
doubt that Dartware will do it. If there are others, then those of us who
don't want it will have voiced out concern that it be an optional switch.
Best regards,
Mike Lieberman

I think turning off the capability is a bad idea. If you are going to
ignore the RFCs, it should always be indicated so that when you leave,
the land mines you create should be flagged.
There are better ways to conserve IP addresses; like using unnumbered
serial interfaces.

off what I believe to be a critical control. Should anyone in our company
try a /31 I want to see it in RED with flares going off!
