Not surprisingly that will drive subnetting in the home. presently, plugging in more gateway/router devices results in multiple layers of nat and huge amounts of unnecessary complexity in the home network. > Clearly, NAT > solves the problem ... while introducing 1000 new ones. :-/ Sure, we don't have a reasonable mechanism for ipv4 devices to pull address space out of thin air. We do have one in ipv6. This is a problem that equipment makers (as much as randy hates them) will have to address. It doesn't take much imagination to figure out how they will address it given a lack of alternatives. > ... JG
