== Introduction ==


'''IPV6''' is '''I'''nternet '''P'''rotocol '''V'''ersion '''6'''.  [[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 ('''I'''nternet '''P'''rotocol) address.   Under the prior version <ref name="IPV4">{{Cite web|url=https://tools.ietf.org/html/rfc791|title=IPV4}}</ref>, IPV4 (Internet Protocol, Version 4), all computers are the internet were assigned a set of decimal numbers.  It would be  12 numbers in all, broken up into four sets of three numbers sperated by a period ( for example 192.168.1.254).    This worked well, however, IPV4 was limited to  4.3 billion addresses that it could hand out before there was no more to hand out.  <p> With everyone now using the internet on their phones, their computers, their laptops, even their Television sets, there just wasn't enough numbers to go around.  So, on July 14, 2017 
<ref name="IPV6">{{Cite web|url=https://www.internetsociety.org/blog/2017/07/rfc-8200-ipv6-has-been-standardized/|title=IPV6}}</ref> was introduced to the web!


== How it works ==
Internet Protocol Version 4 used four set of three decimal numbers  (for example: 192.168.1.254).  Internet Protocol Version 6 uses 8 sets of [[Hexadecimal_numeral_system | hexidecimal numbers ]].   ''"Hexi"'' means 16, and as a matter of fact, the hexidecimal number system counts up to 16.   In the  [[Decimal]] system, we could be able
to count to 16 by counting 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15.  In the hexidecimal system , we would start off normally,  0,1,2,3,4,5,6,7,8,9, '''however''' once we pass "9" we could use A,B,C,D,E,F  for 10,11,12,13,14,15.   For an example of this, please see the table below:<p>
