For a minute there, I thought you might be right since I'm browsing
for clue factor and may have missed something, but, it appears you
are inaccurate in this as the poster did say:
--QUOTE
"If a single-homed network moves from L3 to Cogent, how would they =
benefit? Would=20
they not still be cut off from a significant percentage of the Internet?
Is it reasonable to think that numerous /24's from L3's IP space could =
be=20
reassigned elsewhere without causing significant trouble for L3 and =
others? Even=20
if it could work, what would be the justification for taking L3's =
property?"
--END QUOTE

with them
to another providers network. The answer is yes, it's possible.=20
IANAL
