3.2 How to Configure IPv6 Parameters

You can integrate the TPG into an IPv6 network.

What are the

Advantages of IPv6?

IPv6 (Internet Protocol version 6) is the successor of the more

common IPv4. Both protocols are standards for the network layer of

the OSI model and regulate the addressing and routing of data

packets via a network. The introduction of IPv6 has many benefits:

• IPv6 increases the IP address space from 2

(IPv4) to 2

128

(IPv6)

IP addresses

• Auto Configuration and Renumbering

• Efficiency increase during routing due to reduced header

information

• Integrated services such as IPSec, QoS, Multicast

• Mobile IP

What is the Structure

of an IPv6 Address?

An IPv6 address consists of 128 bits. The normal format of an IPv6

address is eight fields. Each field contains four hexadecimal digits

representing 16 bits.

Each field is separated by a colon (:).

Example:

fe80 : 0000 : 0000 : 0000 : 0000 : 10 : 1000 : 1a4

Leading zeros in a field can be omitted.

Example:

fe80 : 0 : 0 : 0 : 0 : 10 : 1000 : 1a4

An IPv6 address may be entered or displayed using a shortened

version when successive fields contain all zeros (0). In this case, two

colons (::) are used. However, the use of two colons can be used only

once in an address.

Example:

fe80 : : 10 : 1000 : 1a4

As a URL in a Web browser, an IPv6 address must be enclosed in

brackets. This prevents port numbers from being mistakenly

regarded as part of an IPv6 address.

Example: http://[2001:608:af:1::100]:443

1 2 ... 23 24 25 26 27 28 29 30 31 32 33 ... 106 107
