Really Big Numbers

To expand the discussion of Tuesday night concerning IP address,  here are some interesting factoids from Wikipedia:
When we use the internet at the present time we are using IPV4 addresses.  An example of this type of address is an expired dynamic public address once assigned to the Mt. Veeder microwave equipment,
This address is one of many assigned to AT&T and passed out to their customers.  Not long ago, due to the nearly vertical acceleration of technology, it was determined that we would soon run out of possible number combinations.The IPV4 example above uses four 8-bit number groups separated by dots for a total bit count of 32.

IPV6 addresses use 128-bit numbers which will yield 3.4 x 10³8 numbers. That’s 3.4 times 10 followed by 38 zeros! Larger than a billion by several orders of magnitude and spelled duodecillion. That should last us a while. An example of an IPV6 address: 2001:0db8:85a3:0042:1000:8a2e:0370:7334  Current use of IPV6 addresses is around 2% but the number is growing daily.

It all started in 1968 at a small 100 Watt radio station in Napa California. Looks like I finally got my priorities straight: the career is on the back burner and the K3 is getting some air time.
