Head off a potential point of confusion by blocking expandable template
patterns in reverse DNS for IPv6. At best they'll never work the same
way as for IPv4 simply due to the scale of the address space. Could be
considered for /120 and smaller allocations for network infrastructure
someday, maybe. See #1 and #22.
