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 accounts located on the same link.
Unique Local Address
Defined in RFC 4193. Via this address, the IPv6 interface can be reached in the LAN.
Global Unicast Address Via this address, the IPv6 interface can be reached, e.g. via the
Internet.
The interface ID is formed with the EUI-64 method or manually.
Extended Unique Identifier (RFC 4291); method 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 +
+ NIC = AA:BB:CC:
:DD:EE:FF
Defines the range of the IPv6 address.
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
