We are at an end of an era. The age of IPV4 is closing and a new age of IPV6 is fast upon us. The world is effectively out of IPV4 addresses, and IPV6 is not ready for prime time.
While it makes for a dramatic tag line, the switch over to IPV4 to IPV6 will not be a doom and gloom change over. While there are technical hurdles to over come, and today major internet companies are testing their IPV6 networks and infrastructure to find out if they are ready to switch over permanently. The change over will be gradual for most everyone and will happen behind the scenes. Your web host will upgrade and assign an IPV6 address or the new phone you have will have only an IPV6 address. IPV4 are anticipated to be still in use for the next decade or more.
If you haven’t read about the hype regarding the IPV4 to IPV6, here is a quick run down. Internet IP addresses are like a phone number for websites and servers to find each other and talk back and forth. The old numbering system IPV4 has run out of IP addresses that can be assigned out. This was anticipated, but has happened quickly due to the explosive growth of mobile phones (each with their own IP address).
The new system IPV6 sports 340 undecillion numbers. That is a big number, so big that it’s barely conceivable. If you wanted to write it out, it’s 340 followed by 36 zero’s, or to see it typed out:
340,282,366,920,938,000,000,000,000,000,000,000,000 web addresses
To compare this number:
7,000,000,000,000,000,000,000,000,000 (7 octillion atoms in 150lb human)
by 6,000,000,000 (6 billion people alive on earth)
equals 42,000,000,000,000,000,000,000,000,000,000,000,000 (42 undecillion human atoms on earth,)
That’s still 8 IPV6 web addresses for every human atom on the planet!
Needless to say this new numbering scheme will be here to stay for awhile. A bit longer than IPV4′s 20 year run with only 4.3 billion IP addresses.
