/// [RFC 3330] Special-Use IPv4 Addresses
///
/// **Addresses:**
/// - **IPv4:**
///   1. `0.0.0.0/8`: Addresses in this block refer to source hosts on
///       "this" network.  Address 0.0.0.0/32 may be used as a
///       source address for this host on this network; other
///       addresses within 0.0.0.0/8 may be used to refer to
///       specified hosts on this network [RFC 1700, page 4].
///   2. `10.0.0.0/8`: This block is set aside for use in private networks.
///       Its intended use is documented in [RFC 1918].
///       Addresses within this block should not
///       appear on the public Internet.
///   3. `127.0.0.0/8`: This block is assigned for use as the Internet host
///       loopback address.  A datagram sent by a higher level protocol to an
///       address anywhere within this block should loop back inside the host.
///       This is ordinarily implemented using only 127.0.0.1/32 for loopback,
///       but no addresses within this block should ever appear on any network
///       anywhere [RFC 1700, page 5].
///   4. `169.254.0.0/16`: This is the "link local" block.  It
///       is allocated for communication between hosts on a
///       single link.  Hosts obtain these addresses by
///       auto-configuration, such as when a DHCP server may
///       not be found.
///   5. `172.16.0.0/12`: This block is set aside for use in
///       private networks.  Its intended use is documented in
///       [RFC 1918].  Addresses within this block should not
///       appear on the public Internet.
///   6. `192.0.2.0/24`: This block is assigned as "TEST-NET" for use in
///       documentation and example code.  It is often used in conjunction with
///       domain names `example.com` or `example.net` in vendor and protocol
///       documentation.  Addresses within this block should not appear on the
///       public Internet.
///   7. `192.88.99.0/24`: This block is allocated for use as 6to4 relay
///       anycast addresses, according to [RFC 3068].
///   8. `192.168.0.0/16`: This block is set aside for use in private networks.
///       Its intended use is documented in [RFC 1918].  Addresses within this
///       block should not appear on the public Internet.
///   9. `198.18.0.0/15`: This block has been allocated for use
///       in benchmark tests of network interconnect devices.
///       Its use is documented in [RFC 2544].
///   10. `224.0.0.0/4`: This block, formerly known as the Class
///       D address space, is allocated for use in IPv4
///       multicast address assignments.  The IANA guidelines
///       for assignments from this space are described in
///       [RFC 3171].
/// 
///   11. `240.0.0.0/4`: This block, formerly known as the Class E address
///       space, is reserved.  The "limited broadcast" destination address
///       255.255.255.255 should never be forwarded outside the (sub-)net of
///       the source.  The remainder of this space is reserved
///       for future use.  [RFC 1700, page 4]
