About a year ago many Internet service providers and online resources put IPv6 through a test run. And in less than 2 days most of those same IPv6 testers will turn on IPv6 for good. So the question is do you need to worried about this? Most likely not, because the IPv4 protocol that makes up the backbone of the Internet is not going to suddenly shut off, and it’s not going away completely any time soon. The main reason for all of this, is to give plenty of room for growth and enhance security using the IPv6 protocol .

 

If your hardware and software isn’t compatible with IPv6, don’t get worried. IPv6 is backwards compatible with IPv4, and the Internet will continue running both in parallel for some time. You don’t need to run out and get IPv6 equipment this week, but you should definitely make sure any future purchases are ready to work with IPv6.
