Unanswered Question
Mar 27th, 2009

I dont understand the shorthand notation of IPV6 :: How does is work? What does it mean? Especially in multi 16 bit abbreviation eg// 3-4 16 bit chunks. How can u know its replaced 4 16 bits of zeros? Is it anything to do with eui-64? How is eui-64 abbreviated?

What are the different type of multicasts used in ipv6?

Also about WPA2-AES. Why is AES the gold standard? How does AES work?

realll thanks

Hello Balijt,

an ipv6 address is 128 bit in size.

It is expressed as groups of 4 hexadecimal digits.

four hex digits at 0 can be compressed as 0

:0000: :0:

leading zeros can be omitted

:0bcd: can be written as :bcd:

to be able to indicate an ipv6 address without ambiguity the :: can be used only once so by looking at the other groups of hex digits is possible to understand how the :: pattern has to be expanded.

::1ab = 0000:0000:0000:0000:0000:0000:0000:01ab

Hope to help

Giuseppe
