Well.. It’s happened already!

It’s happened a little quicker than we expected. One of our clients requested a new block of IP addresses from their ISP. Guess what, IPv6 addresses were allocated to them with the ISP saying that they didn’t have any IPv4 addresses left.

Fortunately, the client has equipment in the form of firewalls, IPS and routers that can all handle IPv6, however they are now asking serious questions about how IPv6 to IPv4 interworking is going to work.

Equally as fortunately, we’ve been preparing for this and can offer advice and guidance on what will, and won’t work. As we move forward, this is something that a lot of businesses, including ourselves, are going to have to consider.

IP Version 4 Address Exhaustion

The number of available IPv4 addresses available is running out… and quickly. The attached gives a count down to when there will be no new “old” format addresses left to allocate.

IPv6 is out there and available – however there are a load of questions about how it works, and importantly how do IPv6 and IPv4 work together to ensure that you don’t lose access to the web.

Intrinsic Communications has been working on a white paper on what you need to be aware of, and how to prepare yourself for the switchover. Leave us a comment if you’d like to know more.

Update: As of 15/04/2011, it’s looking like all of the IPv4 addresses have gone to the ISPs. What does this mean? Well, short term, nothing is going to stop working overnight, however as we move forward and the ISPs allocate their remaining addresses you won’t be able to get IPv4 adresses for new connections and will only be able to receive IPv6 ones. IPv6 to IPv4 interworking is something that EVERYONE is going to need to understand. The white paper available from Intrinsic Communications takes you through what is and isn’t possible.
