Appendix B IPv6 Subnet Masking Both an IPv6 address and IPv6 subnet mask compose of 128-bit binary digits, which are divided into eight 16-bit blocks and written in hexadecimal notation. Hexadecimal uses four bits for each character (1 ~ 10, A ~ F). Each block's 16 bits are then represented by four hexadecimal characters. For example, FFFF:FFFF:FFFF:FFFF:FC00:0000:0000:0000. Interface ID In IPv6, an interface ID is a 64-bit identifier. It identifies a physical interface (for example, an Ethernet port) or a virtual interface (for example, the management IP address for a VLAN). One interface should have a unique interface ID. EUI-64 The EUI-64 (Extended Unique Identifier) defined by the IEEE (Institute of Electrical and Electronics Engineers) is an interface ID format designed to adapt with IPv6. It is derived from the 48-bit (6-byte) Ethernet MAC address as shown next. EUI-64 inserts the hex digits fffe between the third and fourth bytes of the MAC address and complements the seventh bit of the first byte of the MAC address. See the following example. Table 86 MAC 00 : 13 : 49 : 12 : 34 : 56 Table 87 EUI-64 02 : 13 : 49 : FF : FE : 12 : 34 : 56 Stateless Autoconfiguration With stateless autoconfiguration in IPv6, addresses can be uniquely and automatically generated. Unlike DHCPv6 (Dynamic Host Configuration Protocol version six) which is used in IPv6 stateful autoconfiguration, the owner and status of addresses don't need to be maintained by a DHCP server. Every IPv6 device is able to generate its own and unique IP address automatically when IPv6 is initiated on its interface. It combines the prefix and the interface ID (generated from its own Ethernet MAC address, see Interface ID and EUI-64) to form a complete IPv6 address. When IPv6 is enabled on a device, its interface automatically generates a link-local address (beginning with fe80). When the interface is connected to a network with a router and the Zyxel Device is set to automatically obtain an IPv6 network prefix from the router for the interface, it generates 1another address which combines its interface ID and global and subnet information advertised from the router. This is a routable global IP address. DHCPv6 The Dynamic Host Configuration Protocol for IPv6 (DHCPv6, RFC 3315) is a server-client protocol that allows a DHCP server to assign and pass IPv6 network addresses, prefixes and other configuration information to DHCP clients. DHCPv6 servers and clients exchange DHCP messages using UDP. 1. In IPv6, all network interfaces can be associated with several addresses. NWA/WAC/WAX Series User's Guide 232

Subnet Masking

Both an IPv6 address and IPv6 subnet mask compose of 128-bit binary digits, which are divided into

eight 16-bit blocks and written in hexadecimal notation. Hexadecimal uses four bits for each character

(1 ~ 10, A ~ F). Each block’s 16 bits are then represented by four hexadecimal characters. For example,

FFFF:FFFF:FFFF:FFFF:FC00:0000:0000:0000.

Interface ID

In IPv6, an interface ID is a 64-bit identifier. It identifies a physical interface (for example, an Ethernet

port) or a virtual interface (for example, the management IP address for a VLAN). One interface should

have a unique interface ID.

EUI-64

The EUI-64 (Extended Unique Identifier) defined by the IEEE (Institute of Electrical and Electronics

Engineers) is an interface ID format designed to adapt with IPv6. It is derived from the 48-bit (6-byte)

Ethernet MAC address as shown next. EUI-64 inserts the hex digits fffe between the third and fourth bytes

of the MAC address and complements the seventh bit of the first byte of the MAC address. See the

following example.

Stateless Autoconfiguration

With stateless autoconfiguration in IPv6, addresses can be uniquely and automatically generated.

Unlike DHCPv6 (Dynamic Host Configuration Protocol version six) which is used in IPv6 stateful

autoconfiguration, the owner and status of addresses don’t need to be maintained by a DHCP server.

Every IPv6 device is able to generate its own and unique IP address automatically when IPv6 is initiated

on its interface. It combines the prefix and the interface ID (generated from its own Ethernet MAC

address, see

Interface ID

and

EUI-64

) to form a complete IPv6 address.

When IPv6 is enabled on a device, its interface automatically generates a link-local address (beginning

with fe80).

When the interface is connected to a network with a router and the Zyxel Device is set to automatically

obtain an IPv6 network prefix from the router for the interface, it generates

another address which

combines its interface ID and global and subnet information advertised from the router. This is a routable

global IP address.

DHCPv6

The Dynamic Host Configuration Protocol for IPv6 (DHCPv6, RFC 3315) is a server-client protocol that

allows a DHCP server to assign and pass IPv6 network addresses, prefixes and other configuration

information to DHCP clients. DHCPv6 servers and clients exchange DHCP messages using UDP.
