Don't confuse someone's poor design with design goals.

No, what they often have is multiple layers of nat. I was at a hotel once that had plugged in 12 APs, serially, wan, to lan, to wan, to lan, to wan ports... because the Internet is a series of tubes, right? > You, we, all of us have to stop using the present to limit the future. > What IS should not be used to define what SHOULD BE. > > What people NOW HAVE in their homes should not be used to dictate to > them what they CAN HAVE in their homes, which is what you do when you > provide them only with non-globally-routable address space (IPv4 NAT), > or too few subnets (IPv6 /56) to name just two examples. > > Multiple layers of routing might not be what is now in the home, but it > doesn't take that much imagination to envision a future where there are > hundreds, or even thousands of separate networks in the average home, > some permanent, some ephemeral, and quite possibly all requiring > end-to-end connectivity into the wider Internet.

In my case I have completely abandoned much of the debris of ipv4 and ipv6 - using self assigned /128s and a mesh routing protocol everywhere, giving up on multicast as we knew it, and all I need is one /64 to route my (almost entirely wireless) world. Somehow I doubt this will become a common option for others, but it sure is easier than navigating the slew of standards, configuring centralized services, and casting and configuring limited and highly dynamic ipv6 subnets around. > Regards, K. > > -- > ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ > Karl Auer (ka...@biplane.com.au) > http://www.biplane.com.au/kauer > http://twitter.com/kauer389 > > GPG fingerprint: 3C41 82BE A9E7 99A1 B931 5AE7 7638 0147 2C3C 2AC4 > Old fingerprint: EC67 61E2 C2F6 EB55 884B E129 072B 0AF0 72AA 9882 > > -- Dave Täht worldwide bufferbloat report: http://www.dslreports.com/speedtest/results/bufferbloat And: What will it take to vastly improve wifi for everyone? https://plus.google.com/u/0/explore/makewififast
