IPv6 is in the process of deployment. Search the Internet for the latest news on IPv6 deployment. Report on your findings in a post to this forum. Make sure to include the URL(s) of your source(s). IPV4 is running out of IP address and IPv5 was taken so we have IPv6 which by the end of 2012 there was only 1 percent taken that leaves 99 percent to be used. If you get IPv6 you can’t use it until all of IPv4 is taken. http://arstechnica.com/business/2013/01/ipv6-takes-one-step-forward-ipv4-two-steps-back-in-2012/
