4.1.6 System IPv6

IPv6 (Internet Protocol version 6), also called IPng (IP next generation), was developed by the IETF (Internet Engineering Task Force) as the successor to IPv4 (Internet Protocol version 4). Compared with IPv4, IPv6 increases the IP address size from 32 bits to 128 bits; this solves the IPv4 address exhaustion problem.

IPv6 features

IPv6 has the following features:

1.Adequate address space: The source and destination IPv6 addresses are both 128 bits (16 bytes) long. IPv6 can provide 3.4 x 1038 addresses to completely meet the requirements of hierarchical address division as well as allocation of public and private addresses.

2.Header format simplification: IPv6 cuts down some IPv4 header fields or move them to IPv6 extension headers to reduce the load of basic IPv6 headers, thus making IPv6 packet handling simple and improving the forwarding efficiency. Although the IPv6 address size is four times that of IPv4 addresses, the size of basic IPv6 headers is 40 bytes and is only twice that of IPv4 headers (excluding the Options field).

3.Flexible extension headers: IPv6 cancels the Options field in IPv4 packets but introduces multiple extension headers. In this way, IPv6 enhances the flexibility greatly to provide scalability for IP while improving the handling efficiency. The Options field in IPv4 packets contains 40 bytes at most, while the size of IPv6 extension headers is restricted by that of IPv6 packets.

4.Built-in security: IPv6 uses IPSec as its standard extension header to provide end-to-end security. This feature provides a standard for network security solutions and improves the interoperability between different IPv6 applications.

5.Automatic address configuration: To simplify the host configuration, IPv6 supports stateful and stateless address configuration.

Stateful address configuration means that a host acquires an IPv6 address and related information from a server (for example, DHCP server).

Stateless address configuration means that a host automatically configures an IPv6 address and related information on basis of its own link-layer address and the prefix information advertised by a router.

In addition, a host can generate a link-local address on basis of its own link-layer address and the default prefix (FE80::/64) to communicate with other hosts on the link.

6.Enhanced neighbor discovery mechanism: The IPv6 neighbor discovery protocol is a group of Internet control message protocol version 6 (ICMPv6) messages that manages the information exchange between neighbor nodes on the same link. The group of ICMPv6

19

messages takes the place of Address Resolution Protocol (ARP) message, Internet Control Message Protocol version 4 (ICMPv4) router discovery message, and ICMPv4 redirection message to provide a series of other functions.

Introduction to IPv6 address

1.IPv6 address format

An IPv6 address is represented as a series of 16-bit hexadecimals, separated by colons (:). An IPv6 address is divided into eight groups, and the 16 bits of each group are represented by four hexadecimal numbers which are separated by colons, for example, 2001:0d02:0000:0000:0014: 0000:0000:0095. The hexadecimal letters in IPv6 addresses are not case-sensitive.

To simplify the representation of IPv6 addresses, zeros in IPv6 addresses can be handled as follows:

Leading zeros in each group can be removed. For example, the above-mentioned address can be represented in shorter format as 2001:d02:0:0:14:0:0:95.

Two colons (::) may be used to compress successive hexadecimal fields of zeros at the beginning, middle, or end of an IPv6 address. For example, the above-mentioned address can be represented in the shortest format as 2001:d02::14:0:0:95.

Note:

Two colons (::) can be used only once in an IPv6 address, usually to represent the longest successive hexadecimal fields of zeros. If two colons are used more than once, the device is unable to determine how many zeros double-colons represent when converting them to zeros to restore a 128-bit IPv6 address.

An IPv6 address consists of two parts: address prefix and interface ID. The address prefix and the interface ID are respectively equivalent to the network ID and the host ID in an IPv4 address.

An IPv6 address prefix is represented in "IPv6 address/prefix length" format, where "IPv6 address" is an IPv6 address in any of the above-mentioned formats and "prefix length" is a decimal number indicating how many leftmost bits from the preceding IPv6 address are used as the address prefix.

2.IPv6 address classification

IPv6 addresses fall into three types: unicast address, multicast address, and anycast address.

Unicast address: An identifier for a single interface, on a single node. A packet that is sent to a unicast address is delivered to the interface identified by that address.

Multicast address: An identifier for a set of interfaces (typically belonging to different nodes), similar to an IPv4 multicast address. A packet sent to a multicast address is delivered to all interfaces identified by that address. There are no broadcast addresses in IPv6. Their function is superseded by multicast addresses.

20

Anycast address: An identifier for a set of interfaces (typically belonging to different nodes). A packet sent to an anycast address is delivered to one of the interfaces identified by that address (the nearest one, according to the routing protocols’ measure of distance).

The type of an IPv6 address is designated by the first several bits called format prefix. The following table lists the mappings between address types and format prefixes.

		Type		Format Prefix (binary)			IPv6 Prefix ID
		Unassigned address		00…0 (128 bits)		::/128
		Loopback address		00…1 (128 bits)		::1/128
	Unicast	Link-local address		1111111010			FE80::/10
	address	Site-local address		1111111011			FEC0::/10
		Global unicast address		001			2xxx::/4 or 3xxx::/4
		(currently assigned)
		Reserved type		Other formats
		(to be assigned in future)
	Multicast address			11111111		FF00::/8
				Anycast addresses are taken from unicast
	Anycast address			address space and	are not syntactically
				distinguishable from unicast addresses.
		Table 4-1 Mappings between address types and format prefixes

3.IPv6 Unicast Address

IPv6 unicast address is an identifier for a single interface. It consists of a subnet prefix and an interface ID.

Subnet Prefix: This section is allocated by the IANA (The Internet Assigned Numbers Authority), the ISP (Internet Service Provider) or the organizations.

Interface ID: An interface ID is used to identify interfaces on a link. The interface ID must be unique to the link.

There are several ways to form interface IDs. The IPv6 addresses with format prefixes 001 through 111, except for multicast addresses (1111 1111), are all required to have 64-bit interface IDs in EUI-64 format.

For all IEEE 802 interface types (for example, Ethernet and FDDI interfaces), Interface IDs in the modified EUI-64 format are constructed in the following way:

The first three octets (24 bits) are taken from the Organizationally Unique Identifier (OUI) of the 48-bit link-layer address (the MAC address) of the interface, the fourth and fifth octets (16 bits) are a fixed hexadecimal value of FFFE, and the last three octets (24 bits) are taken from the last three octets of the MAC address. The construction of the interface ID is completed by

21

setting the universal/local (U/L) bit--the seventh bit of the first octet--to a value of 0 or 1. A value of 0 indicates a locally administered identifier; a value of 1 indicates a globally unique IPv6 interface identifier.

Take MAC address 0012:0B0A:2D51 as an example. Insert FFFE to the middle of the address to get 0012:0BFF:FE0A:2D51. Then set the U/L bit to 1 to obtain an interface ID in EUI-64 format as 0212:0BFF:FE0A:2D51.

IPv6 unicast address can be classified into several types, as shown in Table 4-1. The two most common types are introduced below:

Global unicast address

A Global unicast address is an IPv6 unicast address that is globally unique and is routable on the global Internet.

Global unicast addresses are defined by a global routing prefix, a subnet ID, and an interface ID. The IPv6 global unicast address starts with binary value 001 (2000::/3). The global routing prefix is a value assigned to a site (a cluster of subnets/links) by IANA. The subnet ID is an identifier of a subnet within the site.

The figure below shows the structure of a global unicast address.

Figure 4-8 Global Unicast Address Format

Link-local address

A link-local address is an IPv6 unicast address that can be automatically configured on any interface using the link-local prefix FE80::/10 (1111 1110 10) and the interface identifier in the modified EUI-64 format. Link-local addresses are used in the neighbor discovery protocol and the stateless autoconfiguration process. Nodes on a local link can use link-local addresses to communicate. The figure below shows the structure of a link-local address.

Figure 4-9 Link-local Address Format

IPv6 devices must not forward packets that have link-local source or destination addresses to other links.
