I use legacy IPv4 space and pay nothing. So IPv6 would be a big jump. Didn't even need to invoke NAT for my argument. But I'll repeat what I said before - want ISPs handing out lots of space? Make the minimum /20 or /24 instead of /32. I'll support that over on the other list if someone proposes it. Matthew Kaufman (Sent from my iPhone)
