On Thu, 17 Aug 1995 14:57:40 -0700 (PDT) you said:
Does that mean that all the internet registries no longer allocate
/24 (or longer) prefixes that have nothing to do with the actual
Internet topology (these prefixes aka "portable addresses") ?  Perhaps
folks from various Internet registries would be able to answer this
question.

I assign /22s to ISPs.  When they use them up I give them another /22.
Private companies that show a need for a /24 are assigned a /24.


Ah. here is the rub.  When you ISP buddies come back, you should ask
them to return the origianal /22 for a /20.  That way, the total size
of the routing system stays the same!

Great idea.  Know ANYONE who does that?  The best I can do is give them a
/20 (in addition to the original /22) if their growth warrants it.
