>A pox on it. We need IPv7 - just add another octet at the start of IPv6..
Couldn't we add one onto IPv4 instead and keep the rest of it the same? Then the hard-won skills of a multitude of consumer grannies (and me) could be transferred and nobody has to play how-many-colons bingo with that ridiculously opaque address scheme. Worked pretty well when we needed more phone numbers, amirite?
