IPv6 - how many addresses is that exactly?

Ever wondered how many addresses are possible using IPv6?  I wanted to know and thought I would share with you.  IPv6 can have 2^128 IP addresses.  That is a lot and if you are wondering how many that is exactly…2^128 = 340,282,366,920,938,463,463,374,607,431,768,211,456.  Now the question is, can you say that number out loud or even in your head?

Okay, take a deep breath and say after me - “340 undecillion, 282 decillion, 366 nonillion, 920 octillion, 938 septillion, 463 sextillion, 463 quintillion, 374 quadrillion, 607 trillion, 431 billion, 768 million, 211 thousand and 456″

Okay all you network junkies…try filling that address range up.
