Four Root DNS Servers Go IPv6 On February 4th

Posted by Zonk on from the our-interwebs-are-all-growed-up dept.

I Don't Believe in Imaginary Property writes "On February 4th, IANA will add AAAA records for the IPv6 addresses of the four root servers. With this transition, it will finally be possible for two internet hosts to communicate without using IPv4 at all. Certain obsolete software may face compatibility problems due to the change, but those issues are addressed in an ICANN report (pdf)."

    The main problem isn't obsolete software, but hardware. Changing routers to some that support IPv6 isn't done over night. And even if you do, and get IPv6 assigned, it doesn't help unless your provider also supports IPv6 -- else you might as well be tunelling the old way anyhow.

    Great, now we can soon get on with the job of assigning static ip addresses to all our toasters, refrigerators, furnaces, thermostats, tv sets, electric hairdryers, etc.

      What is so difficult about adding a default rule to your firewall that blocks all incoming connections to your subnet and then adding rules specifically for the devices and services that do require incoming connections?

      ie) deny ip from any to 2610:78:ad::/48

      With NAT you are eliminating the possibility of incoming connections, with IPv6 you can deny connections all you want but can allow incoming connections where required or desired. Sure you can setup a port forwarding rule to allow a service for a given machine, but what happens when you need the same service to go to more than one host? You know need to accommodate for that by changing the incoming port on your real IP.

      Not to mention all the issues raised by protocols that embed IP's that are not routable within the protocol themselves (take the SIP protocol for example). Work-arounds need to be put in place for many protocols on an individual basis in a NAT'd environment. This is a pain in the ass that would be highly unnecessary in a post IPv4 world.

      If you're so fond of the kludge that is NAT, nobody is stopping you from using NAT with IPv6 in combination with a non-routable unique-local prefix (fc00::/7).

      Dragging your feet on adoption of a superior technology that works for every situation in favor of a broken setup that happens to meet YOUR rather limited requirements is delaying progress for the rest of us. ;)

      Generally speaking the consumer world isn't ready for IPv6 yet anyway (Too many Windows machines with limited IPv6 capabilities)... but I still get annoyed with all the anti-IPv6 commentary by those that have not fully investigated the specifics.

      Just the personal pet peeve that is looking forward to moving behind the network design of choice for the 1980's.

    They don't do dynamic IP addresses because they don't have enough addresses. They do it for stopping you from running a server on your home computer. Sure you can still run a server, but it's harder to run one when your IP address keeps changing.
