It’s official the end is near…

Today the rest of the IPv4 address have been distributed out to the five Regional Internet Registries (RIR).  What does this really mean? For regular users it means nothing. For businesses it means if they are not ready for IPv6 then they need to do so.  They can do this with transitional technologies such as dual stack, dual-IP stacks, and Dual Stack Application Level Gateways that will let you use IPv4 and IPv6 at the same time. Wikipedia has some information on what exactly dual-IP-stacks are.

The good news about this is we wont have to worry about this happening again for a long time since IPv6 uses 128bit addresses so there are about 3.4 duodecillion which translates out to 340,000,000,000,000,000,000,000,000,000,000,000,000,000. I am pretty sure that should be enough for our life time.

The bad news is that it is pretty hard to remember the addresses. We will be going from 192.168.1.1 to 3ffe:1900:4545:3:200:f8ff:fe21:67cf .

So now is the time to prepare as the end of IPv4 is happening soon and we will be in the IPv6 era.
