What is a unique address?

A unique local address (ULA) is an Internet Protocol version 6 (IPv6) address in the address range fc00::/7. Its purpose in IPv6 is somewhat analogous to IPv4 private network addressing, but with significant differences.

What are the 3 types of IPv6 addresses?

The three types of IPv6 addresses are: unicast, anycast, and multicast. Unicast addresses identify a single interface.

What does FC00 ::/ 7 mean?

The FC00::/7 prefix is reserved for unique local addresses, however when you implement this you have to set the L-bit to 1 which means that the first two digits will be FD. Here's an example: Let's discuss all the fields of the unique local address. The first 7 bits indicate that we have a unique local address.

Are IPv6 addresses unique?

Before jumping into details, there are a few key features IPv6 incorporates: IPv6 uses 128-bit (2¹²⁸) addresses, allowing 3.4 x 10³⁸ unique IP addresses. This is equal to 340 trillion trillion trillion IP addresses.
