I am often asked about IPv6, especially as it relates to the 8e6 product line. For those that are unfamiliar with IPv6, it’s a new IP protocol that will replace the current IPv4 protocol at some point in the future. The major driver for the transition to IPv6 is the total number of available IP Addresses. With the current IPv4 protocol the total number of IP addresses available is 4,294,967,296 (2³²).

When IPv4 was originally envisioned the primary users of IP Addresses were research facilities and governments. As more business joined the online community, they of course needed IP Addresses as well. In the 90s there was an explosion in the number of IP Addresses allocated to home users for Internet access from home computers. Now we are seeing more devices using IP Addresses. Cell Phones, wireless e-Books, and wireless MP3 players are now using IP Addresses in order to communicate online.

The problem is that at some point in the future we will simply run out of available IPv4 Addresses. IPv6 on the other hand supports 2¹²⁸ (about 3.4×10³⁸) or (3.4 times 10 with 38 zeros following.) That would leave approximately 5×10²⁸ IP addresses for each and every person alive on our planet today. Needless to say, that’s a lot of addresses.
