In my earlier post about John Williams' talk at SAP there was some mention of "Internet of things" that I felt made for an important point about the future of IP provisioning.
Today, Gary Hemminger from Foundry Networks gave a presentation at SAP about IP V6 and its implications on Enterprise Applications that I felt was a continuation of discussion started by John earlier this year.
Some detailed history on IP V6 is available here. The summarized version is that in 1992 the end alls and be alls decided that IP addresses will run out at some point at the pace they were going.
IP V4 uses 32 bits for address while IP V6 uses 128 bits. Just to give you an idea, that means IP V4 gives you about 4 Billion nodes and IP V6 gives you about 340,282,366,920,938,463,463,374,607,431,768,211,456.
The larger space is only one positive afteraffect. There is more good with Security and Network address simplicity. Current IP address allocation is pretty lopsided with US coroporations and organizations getting the lion's share. IP V6 provides a solution to that problem as well. This widget shows the clock running out on the IP addresses.
Here are the problems though:
IP V6 will need some building blocks such as Operating Systems, the Networks and the applications. More on that in the next post.....
