In a nutshell,
IPv6 addresses are 128-bit, which means we have a pool of 2^128 addresses to use. That is 340,282,366,920,938,463,463,374,607,431,768,211,456, or 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 addresses.
Which should be just about enough for the Internet of Insecure Intrusive Gratuitously Connected Things.
