Structure Of An Ipv6 Address - Siemens SCALANCE W1780 Configuration Manual

IP addresses
5.3 IPv6 address
LLA
Link local address FE80::/10
As soon as IPv6 is activated on the interface, a link local address is formed automatically. Can
only be reached by nodes located on the same link.
ULA
Unique Local Address
Defined in RFC 4193. The IPv6 interface can be reached via this address in the LAN.
GUA
Global Unicast Address The IPv6 interface can be reached through this address, for example,
via the Internet.
Interface ID
The interface ID is formed with the EUI-64 method or manually.
EUI-64
Extended Unique Identifier (RFC 4291); process for forming the interface ID. In Ethernet, the
interface ID is formed from the MAC address of the interface. Divides the MAC address into the
manufacturer-specific part (OUI) and the network-specific part (NIC) and inserts FFFE between
the two parts.
Example:
MAC address = AA:BB:CC:DD:EE:FF
OUI = AA:BB:CC
NIC = DD:EE:FF
EUI-64 = OUI + FFFE + NIC = AA:BB:CC:FF:FE:DD:EE:FF
Scope
Defines the range of the IPv6 address.
5.3.2

Structure of an IPv6 address

IPv6 address format - notation
IPv6 addresses consist of 8 fields each with four-character hexadecimal numbers (128 bits in
total). The fields are separated by a colon.
Example:
fd00:0000:0000:ffff:02d1:7d01:0000:8f21
