RE: was bogon filters, now "Brief Segue on 1918"

But ... that's part of why RFC1918 is used, so they have this fairly large
address range to play with.
        And remember, what one person calls inefficiency, another calls
flexibility.  Either (or neither) may be right!

Oh, and I don't think we can say RFC1918 doesn't work today - obviously it
does, just possibly inducing lots of head-aches.


And yes, same ideas occur - just with larger numbers :) - in v6.
        To keep the analogy complete, reference ULAs ... with a (more
stringent?) random component.
        (I put a question mark on that just because you can break the spec
and configure non-random ones <grumble>)

Actually, rereading this, I agree.  My experience is large companies take
it
all, using huge swathes inefficiently, instead of doing it right.  In my
previous post I was answering the question I thought you were asking, not
your real question.

I agree with you both.

I think that RFC1918 Could work, if companies used it correctly....  Again,
though, I have only run into one company that used it correctly.  IPV6, you
are our only hope! (obiwan kenobi, you are our only hope!)

How much of 10/8 and 172.16/12 does an organization with ~80k
employees, on 5 continents, with hundreds of extranet connections to
partners and suppliers in addition to numerous aquistions and the
occasional subsidiary who also use 10/8 and 172.16/12 use?

In my experience, effectively all of it.
