Explanation:
A unique local address (ULA) is an IPv6 address in the block fc00::/7, defined in RFC 4193. It is
the approximate IPv6 counterpart of the IPv4 private address. Unique local addresses are
available for use in private networks, e.g. inside a single site or organization or spanning a limited
number of sites or organizations. They are not routable in the global IPv6 Internet.
