Actually, no, not really. When you're dying of thirst, even muddy water =

Such folks will also have to take into consideration opportunity cost. =
Or they could make the strategic decision that all they really need is =
one or two ISP-provided public IPv4 addresses (in addition to IPv6) for =
their NATv4 box and public servers is all they really need and lease to =
their ISP the blocks they currently have in exchange for free =
connectivity or whatever. Etc. Myriad of possibilities.
The point is that when the IPv4 free pool is exhausted, there will be =

to apply. I've been disappointed that some folks in the RIR communities =
