Last time I checked I found these interesting records while checking
Alexa top 1 million domains:

 2 UNIQUE-LOCAL-UNICAST
 4 TEREDO
 6 DOCUMENTATION
 7 UNSPECIFIED
37 RESERVED
47 LINK-LOCAL-UNICAST
62 LOOPBACK
95 IPV4MAP
223 6TO4

Perls net::ip will put the NAT64 prefix under the RESERVED category.
