Not really, I just love sensational titles! So there’s allot of noise being made recently about the IPv6 changeover; when it should happen, how, etc. and the consensus is that we’ve already waited too long and we are pretty much boned. That is to say, we don’t have enough time to make the IPv4 to IPv6 transition go smoothly.
For those of you unfamiliar with how ip addressing and the internet works, more specifically how the numbers are handled. that job falls to the NRO (Number Resource Organization) which was formed by the RIRs (Regional Internet Registries) to “protect the unallocated Number Resource pool, to promote and protect the bottom-up policy development process, and to act as a focal point for Internet community input into the RIR system” which basically means, they’re the guys who release IP blocks and addresses to the IANA (Internet Assigned Numbers Authority) who then hands these over to the RIRs, who will distribute them to the LIR (Local Internet Registries – usually an ISP), who then gives you the end user your ip address.
Sounds like a big mess but each step is very important for managing our addressing space. So here’s the bad news. The NRO warns that only 10% of the IPv4 addressing space is unused. Meaning, there’s very very little room for more addressing under our current system. DOOMED!!!!!
Well not entirely. IPv6 is here to save the intarwebs! It allows for a possible 340,282,366,920,938,463,463,374,607,431,768,211,456 addressed. So we will not have any issues like this anymore. The next problem will be the conversion. Which if you’re reading this you probably have no control over; this is a job for the big guys to sort out: the ISPS and backbone folk. But one thing is for sure, the transition should already be underway if it was going to go unnoticed. It’s going to be a bumpy road, but by 2012 you should have a whole new IP address to memorize!
