How to Configure IPv6 Parameters
You can integrate the UTN server into an IPv6 network.
What are the
Advantages of IPv6?
IPv6 (Internet Protocol version 6) is the successor of the more com-
monIPv4. 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
32
(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 ver-
sion 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
The URL will only be accepted by browsers that support IPv6.
