Global IPv6 shakedown - running out of IP addresses
To those who don't know it, June 8th, 2011 is IPv6 Internet shakedown test. It seems globally we have run out of IP addresses with IPv4. Industry has been twiddling their collective thumbs on changing over to IPv6 to solve the problem but most of your consumer equipment along with the firewalls is not compatible with IPv6! Most of your modern operating systems are but those wireless routers with the pretty twinkling lights and your DSL modem (yikes!) are not!
So will those Actiontec M1000's, Q1000's, and plethora of other Qwest subscriber equipment work with IPv6, no. Are they firmware upgradable? Some. Will this cause problems and unforeseen expenses in the future? It could, especially for gamers, VOIP, and point to point file sharing.
Why? You might have to share the same IP address instead of having a unique address to you. Maybe thirty two people will share the same address as you just as your home router shares all your connections on a single WAN address to the outside world. All those people sharing the "party line" data may tend to get mistranslated.
Why might this happen? It is cheaper to use carrier grade address translation than truly converting to IPv6.
