Re: "We have now run out of IPv4 addresses"
"Just tack on four more bytes, and consider that the existing IPv4 space was simply 127.0.0.0.x.x.x.x"
Honest question - why can't we do this?
Obviously(?) it would only be possible to use it if everything between clients was doing the same thing, but is it possible to run your own protocol in a similar way to the fact that it's possible to run your own DNS without any reference to the root servers?
