Today we were discussing the transition from IPv4 to IPv6 that I noted yesterday. To me, one of the amazing numbers in this effort are the number of IP addresses that IPv6 enables, as I noted in the post...

Realizing that eventually these IPv4 addresses would be exhausted, Internet Protocol version six (IPv6) was mapped out in the 1990's and then published in 1998 as the next step in IP.  IPv6 is 128-bit, which provides support for many more devices. 3.4 to the 128th, to be exact, or 340,282,366,920,938,463,463,374,607,431,768,211,456 IP addresses. That should be enough for a few more years.

So I thought: how many IPv6 devices would that be for every person on the planet today. Assuming 7 billion people, I believe that equates to be approximately 428 octillion (or 428 billion billion billion, 4.28×1028).

Or in other words, IPv6 is enough for everyone to have 428 octillion IP enabled devices.

Please note that math was not my major and subject to correction. ;)
