IPv6 Address types
Link-Local Address
- Prefix: fe80::/10
Link-Local addresses are used on a single link such as an Ethernet LAN. They do not need to be unique outside of that link.
Link-Local
IPv6 Address Type: | Link-Local |
Prefix: | fe80::/10 |
Local Routeable: | No |
Global Routeable: | No |
Global Unique: | No |
Example: | FE80::21B:D4FF:FE0F:8CA2 |
IPv4 Equivalent: | 169.254.0.0/16 Link-Local |
Explanation
These addresses are used on a single link or a non-routed common access network, such as an Ethernet LAN.
They do not need to be unique outside of that link.
Link-local addresses may appear as the source or destination of an IPv6 packet.
Routers must not forward IPv6 packets if the source or destination contains a link-local address.
Unique Local Address (ULA)
IPv4-Mapped
6to4
Global Unicast
Multicast
Loopback Address
- Prefix: ::1/128
Same function as
Unspecified Address
- IPv6 Prefix: ::/128
- Compare to IPv4: 0.0.0.0
May only be used by Hosts as Source address before it has learned it's own IPv6 address.
