It's hard to believe that IPv6 is 14 years old, yet I don't personally know a single company that has migrated to it. I did some quick research and found that quite a few companies are using IPv6 or are IPv6 ready, meaning they have the infrastructure in place. Google, Sprint, AT&T, Comcast, Verizon, China, Japan, Korea, and several federal agencies claim to be using the new address space.
What are some of the security implications of moving to IPv6?
What are the advantages of going to IPv6? Here are just a few:
So why aren't more companies using it? To answer that question, we have to look at why IPv6 was developed. The new addressing protocol was developed because we thought we were running out of IP addresses. When the specification was first released in 1995, we thought we would be out of addresses by 2005. It looked like the sky was falling. 2005 came and went and we didn't run out of addresses. Here we are in 2009 and the estimate is now that by 2012, we will be out of addresses. The Internet Engineering Task Force (IETF) is working on methods to help with the transition to IPv6. These include:
When we look at these methods, what we really see are the ways that will yet prolong the use of IPv4. Who knows when this nonsense will end? Companies need to bite the bullet and make the switch.
Yes, there are a few minor disadvantages to going to IPv6:
I am not saying that the sky is falling, but would it help if I said it was? When is your organization going to switch to IPv6?
