We would need blacklisting/graylisting for the 1.2.3.4. The current
code implements graylisting for SRV records (by manipulating their
priority, if I recall correctly). However, there is no priority
associated with A records, so we would need a different solution.
Perhaps a list (or binary tree or hash table or ...) of bad IP
addresses/ports/protocols?
