IPv6 introduces a 128 bit IP address for both source and destination address fields.

This means that there are 2^128 addresses possible with that many bits.

2020 05 21 15 46 58

As shown, 2^128 is about 340,282,366,920,938,000,000,000,000,000,000,000,000

[The actual number is shown in the comments below]

I have long contended that I have no idea how to read that number.  I usually say something like "a lot".

But - thanks to one of my students (Thank You Bobby) the answer is now provided:

"Three hundred forty undecillion, two hundred eighty two decillion, three hundred sixty six nonillion, nine hundred twenty octillion, nine hundred thirty eight septillion."

One word - WOW!

Is it enough?  Will it be enough?  Comment below....
