Didn't the internet start out as a Network of Network. Then there was a time when it became popular to the general public, and everyone was happy when he had one single PC with a modem to connect to the internet. Today we're back to where it started, the internet is a network of (local) networks, and it is important to keep the networks properly seperated because of the unbounded growth of features and bugs/vulnerabilities in popular operating systems for the computer novice. The average DSL home route does more than just NAT, it is a DHCP server vor a private address space, a DNS server that fakes locally assigned/claimed hostnames into the DNS name resolution (and continues to work even if the internet link is down). You really do not want devices of everyones home network (e.g the admin web interface of your DSL router, your NAS, your set-top-box, etc. to becomme freely accessible from everywhere on the internet, because it is likely close to impossible to preconfigure new home&entertainment devices in a fashion that they're securely accessible only to their rightful average non-security-geek owners and nobody else, and it will be entirely impossible to convert any of the existing installed base of devices into such a fully-accessible-for-owner and 100%-inaccessible-for-everybody-else configuration. If IPv6 does not offer the the same properties as the current IPv4 internet subscription for the average home user -- which implies NAT, private local network and smooth local operation when the internet is down -- then very few will want IPv6 to their homes (I certainly wouldn't want it), and IPv6 adoption will continue to drag along for several years. > > How do you think about P2P applications?
