IPv4 is a 32-bit addressing scheme that allows 4,294,967,296 possible unique addresses. IPv6 is a 128-bit addressing scheme that allows much more.

This is the number of possible IPv6 numbers that are possible:
340,282,366,920,938,463,463,374,607,431,768,211,456

And here is how to say the number.

340- [tag]undecillion[/tag]
282- [tag]decillion[/tag]
366- [tag]nonillion[/tag]
920- [tag]octillion[/tag]
938- [tag]septillion[/tag]
463- [tag]sextillion[/tag]
463- [tag]quintillion[/tag]
374- [tag]quadrillion[/tag]
607- [tag]trillion[/tag]
431- [tag]billion[/tag]
768- [tag]million[/tag]
211- [tag]thousand[/tag]
456

HOW BIG IS THAT REALLY??!

2^128=340,282,366,920,938,463,463,374,607,431,768,211,456 = 3.4×10^38
– 50 octillion addresses for each of the 6.5 Billion people on earth
– Every atom in the human body could have IPv6 address
– Windshield wipers on your car may have and IPv6 address (every device can be “pingable”)

Pros and Cons of IPv6:

CON
• Lack of migration plan
• Definition of “compliance”? (dod)
• Long address (2001:0000:1080:8c88:8:800:200C:417A)
• Security issues

• No tools to check IPv6 packets, so this exploit has no way to be stopped yet
– Windows XP supports IPv6 but the SP2 firewall would not detect rogue data inside ICMPv6 packets

PRO
• ipv6 for everything
• Japan already on top of it
• Help countries like China and India
