3.2 How to Configure IPv6 Parameters
You can integrate primos 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
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 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
Note
The URL will only be accepted by browsers that support IPv6.
Which Types of
IPv6 Addresses
Are Available?
There are different types of IPv6 addresses. The prefixes of the IPv6 addresses provide
information about the IPv6 address types.
• Unicast addresses can be routed globally. These addresses are unique and therefore
unambiguous. A packet that is sent to a unicast address will only arrive to the interface
that is assigned to this address. Unicast addresses have the prefixes '2' or '3'.
• Anycast addresses are assigned to more than one interface. This means that a data
packet that is sent to this address will arrive at various devices. The syntax of anycast
