Hi everyone,
I am confused in IPv6, i was research some RFC but certainly i dont knows if i choose the correct. i need to configure some cisco stuff with IPv6 and i want to know what ipv6 use for private and public.
Unique local for private (https://tools.ietf.org/html/rfc4193)
| 7 bits |1| 40 bits | 16 bits | 64 bits |
+--------+-+------------+-----------+----------------------------+
| Prefix |L| Global ID | Subnet ID | Interface ID |
+--------+-+------------+-----------+----------------------------+
Where:
Prefix FC00::/7 prefix to identify Local IPv6 unicast
addresses.
L Set to 1 if the prefix is locally assigned.
Set to 0 may be defined in the future. See
Section 3.2 for additional information.
Global ID 40-bit global identifier used to create a
globally unique prefix. See Section 3.2 for
additional information.
Subnet ID 16-bit Subnet ID is an identifier of a subnet
within the site.
Interface ID 64-bit Interface ID as defined in [ADDARCH].
Global unicast for pyblic (https://tools.ietf.org/html/rfc3587)
| 3 | 45 bits | 16 bits | 64 bits |
+---+---------------------+-----------+----------------------------+
|001|global routing prefix| subnet ID | interface ID |
+---+---------------------+-----------+----------------------------+
Site-Local is depreceated (https://tools.ietf.org/html/rfc4291#section-2.5.7)
