NET 4000 Chapter 11.3.2: 11.3.2 IPv6 Facts
Document Summary
Ip version 6 (ipv6) is an updated version of the ip protocol designed to address the shortage of registered ipv4 addresses. The ipv6 address is a 128-bit binary number. A sample ipv6 ip address looks like: 35bc:fa77:4898:dafc:200c:fbbc:a007:8973. The following list describes the features of an ipv6 address: The address is made up of 32 hexadecimal numbers, organized into 8 quartets. Each quartet is represented as a hexadecimal number between 0 and ffff. Each quartet represents 16-bits of data (ffff = 1111 1111 1111 1111). Leading zeros can be omitted in each section. For example, the quartet 0284 could also be represented by 284. Addresses with consecutive zeros can be expressed more concisely by substituting a double-colon for the group of zeros. If an address has more than one consecutive location where one or more quartets are all zeros, only one location can be abbreviated. The first 64-bits is known as the prefix.
