== Introduction ==


'''IPV6''' is '''I'''nternet '''P'''rotocol '''V'''ersion '''6'''.  [[Internet_Protocol|Internet Protocol]] is a system that allows each computer to be identified on the internet.  Each computer is  issued a numeric  (a number that identifies the computer, like your address identifies your house)  address called an I.P ('''(contracted; show full)

IPV4:  '''4,294,967,296  addresses possible ''' <br>
IPV6:  '''340,282,366,920,938,463,463,374,607,431,768,211,456 addresses possible''' <br><br>


In short, a ''great'' deal more addresses are available with this system. 

Also, IPV6 allows for multicasting, that is, sending one network packet to multiple computers with one request.  This would be like writing a letter (which would be what the packet actually is, the letter), dropping it in one envelope and having it reach many different people in many different locations at the same time.   IPV4 ''can'' multicast, ''but'' it's not something that's normally a part of IPV4, it has to be added in to work. IPV6 has multicasting already a part of itself.

It can also automatically set up addresses for different computers on a network. IPV4 can do this as well, but it needs assistance from the router, IPV6 doesn't need assistance, it already knows what it needs to do , out of the box, so to speak!

IPV4 had no real privacy settings in it, your IP address could link right to you. IPV6 ''has'' privacy built in, in the form of a helper program that works by generating random addresses then letting them go after a certain period of time.


== Address format ==

IPV6 has an address format to it.  The first 64 bits are the network's identifier.  Those bits will remain the same for each network,  for example, if the IPV6 address is:<br><br> 2001:0000:3238:DFE1:0063:0000:0000:FEFB <br><br>  the first 64 bits would be <br><br> 2001:0000:3238:DFE1.  The second set of 64 bits would be

== How it's organized ==

IPV4 addresses were set up to show the server's IP address ( for example,
