Link-Local Unicast Address Layout The following represents the link-local unicast address layout: The first 10 bits of the address prefix identify an address as a link-local address: 1111 1110 10 in binary fe8 in hexadecimal The remainder of the prefix is padded with 54 bits of zeros and is followed by the 64-bit Interface ID. Example (compressed): The prefix is fe80:: and the Interface ID is a00:20ff:feb5:4137. Link-local addresses are not forwarded by routers. fe80::a00:20ff:feb5:4137 Thomas Xavier ([email protected]ฺcom) has a non-transferable license to use this Student Guideฺ Unauthorized reproduction or distribution prohibitedฺ Copyright© 2017, Oracle and/or its affiliatesฺ
The format of a global unicast address includes the following: Global routing prefix: A value assigned by an address registry or ISP to identify a site. Its size is variable. Subnet ID: An identifier of a subnet or link within a site. The number of bits in this field depends on the size of the global routing prefix. Interface ID: The 64-bit portion of the IP address that identifies the interface. The number of bits within the Global Routing Prefix and Subnet ID parts of the address can vary, but they should add up to 64 bits total the total size of the prefix (Global Routing Prefix + Subnet ID). The example shows a 48-bit Global Routing Prefix of 2001:db8:0 . Note that this is the documentation prefix and is used for purposes of the example. A routable prefix would be different. The Subnet ID is the 16-bit hexadecimal number 0x6 (shortened from 0006 ), giving an overall prefix length of 64 bits. the Interface ID is the 64-bit hexadecimal number a00:20ff:feb5:4137 . Note that the leading zero of the first hextet in the interface ID is omitted, so 0a00 is presented as a00 .

Global Unicast Address Layout The following represents the global unicast address layout: The first three bits are always set to 001 (binary), 0x2 (hexadecimal) Global routing prefix size is variable. Value is assigned by an address registry or ISP to identify a site. Subnet ID size is dependent on the size of the Global Routing Prefix. Identifier of a subnet or link within a site, assigned by a system administrator Global routing prefix size + subnet ID size = 64 bits Interface ID uniquely identifies an interface and is 64 bits in size Example with a 48-bit Global Routing Prefix, 16-bit Subnet ID, and 64-bit Interface ID: 2001:db8:0:6:a00:20ff:feb5:4137 Global Routing Prefix Subnet ID Interface ID Thomas Xavier ([email protected]ฺcom) has a non-transferable license to use this Student Guideฺ Unauthorized reproduction or distribution prohibitedฺ Copyright© 2017, Oracle and/or its affiliatesฺ
The multicast address type allows many systems to be members of a multicast group, which is represented by a single multicast address. An IPv6 multicast address can be thought of as a single
