No, what they often have is multiple layers of nat. I was at a hotel=20

In my case I have completely abandoned much of the debris of ipv4 and=20
ipv6 - using self assigned /128s and a mesh routing protocol=20
everywhere, giving up on multicast as we knew it, and all I need is=20
one /64 to route my (almost entirely wireless) world.=20
Somehow I doubt this will become a common option for others, but it=20
sure is easier than navigating the slew of standards, configuring=20
centralized services, and casting and configuring limited and highly=20
dynamic ipv6 subnets around.=20
