How Ready Is IPv6 To Succeed IPv4?

Posted by timothy on from the depends-what-you-want-to-do-with-it dept.

New submitter unixisc writes: Over the last 2 years, June 6th had been observed as IPv6 day. The first time, IPv6 connections were turned on by participants just for a day, and last year, it was turned on for good. A year later, how successful is the global transition to IPv6? According to Cisco 6labs, adoption rates vary from 50% in Belgium to 6% in China, with the U.S. coming somewhere in the middle at 37%. A lot of issues around IPv6, such as the absence of NAT, have apparently been resolved (NAPT is now available and recognized by the IETF). So what are the remaining issues holding people up — be it ISPs, businesses, consumers or anybody else? When could we be near a year when we could turn off all IPv4 connectivity worldwide on an IPv6 only day and nobody would notice?

    Absence of NAT is a feature! If not THE feature of IPv6!

      NAT has no security benefits. NAT's sole purpose is address scarcity. Firewalls are for firewalling. NAT is for breaking the pre-IPv6 internet out of necessity.

      My home subnet is 2610:1e8:800:101::/64. Go ahead and tell me how many machines are in there...

      I'll wait.

      Without NAT, you're still hitting the stateful firewall and default deny rule at the edge of my network... Most home routers should default to this sort of behaviour.

      The difference is, I can open up as many ports as I need with no limitations. None of this crap with forwarding port 80 to one box and then... Oh, I need another web server... Hmm. 8080? Other random / arbitrarily selected ports? That sucks! It's broken.

      The IPs I'm leaving in web server logs are also throw-away addresses - read up RFC-4961.

      you're ignoring gamers and people using skype or other direct message programs just to begin with, because of NAT you can't have 2 xboxes online on the same internet connection. NAT is a fucking cancer that needs to be cut out.
