Loopback
A loopback address (0:0:0:0:0:0:0:1 or ::1) allows a host to send packets to itself. It is similar to
"127.0.0.1" in IPv4.
Unspecified
An unspecified address (0:0:0:0:0:0:0:0 or ::) is used as the source address when a device does
not have its own address. It is similar to "0.0.0.0" in IPv4.
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.
