      ok... so is it -just- me that gets the willies thinking of the
      2x64-1 available IPv6 addresses that can be forged as source
      addresses for spam origination?    i REALLY want to have a tidy

but, but, but... ipv6 is more SECURE! :) I'm really not sure I understand
why my LAN has to have more available ip space than the current Internet,
but boy, it sure makes it easy to spam^H^H^H^Hfind available addresses!

I view the 48/56/64 boundaries about like Woody does (and I suspect Mr.
Narkins and Mr. Bush) they are in the documentation so people use them,
it's not particularly a great idea, but it is an idea. (Oh, and some
equipment won't do the lovely autoconfig unless you have a /64, someone
should open a bug report on that)
