Structure of the IPv6 address
The IPv6 protocol distinguishes between three types of address: Unicast , anycast and
multicast. The following section describes the structure of the global unicast addresses.
Global prefix:
Subnet ID
Interface ID
Assigned address
range
Description of the location, also
subnet prefix or subnet
Unique assignment of the host in the net-
work.
The ID is generated from the MAC ad-
The prefix for the link local address is always fe80:0000:0000:0000. The prefix is shortened
and noted as follows: fe80::
Specified in: RFC 4291
The IPv6 prefix represents the subnet identifier.
Prefixes and IPv6 addresses are specified in the same way as with the CIDR notation
(Classless Inter-Domain Routing) for IPv4.
IPv6 address / prefix length
IPv6 address: 2001:0db8:1234::1111/48
Prefix: 2001:0db8:1234::/48
Interface ID: ::1111
The entry of IPv6 addresses is possible in the notations described above. IPv6 addresses
are always shown in the hexadecimal notation.
