 * the registry leaves the column blank and the block inherits the answer of
 * the block containing it (or is global when nothing contains it).
 *
 * `Address4.isGlobal()` answers from the most specific entry containing the
 * address. `test/data/iana-corpus.json` is generated from the registry's CSV
 * and pins this table to it.
