/**
 * The IANA IPv6 Special-Purpose Address Registry
 * (https://www.iana.org/assignments/iana-ipv6-special-registry/), one entry
 * per block: `[cidr, name, globallyReachable]`. A `null` reachability means
 * the registry says N/A or leaves the column blank; N/A blocks (Teredo, 6to4)
 * are treated as not globally reachable, since a packet to one needs a relay,
 * and blank blocks inherit the answer of the block containing them.
 *
 * `Address6.isGlobal()` answers from the most specific entry containing the
 * address, after delegating IPv4-mapped and NAT64 well-known addresses to the
 * embedded IPv4 address. `test/data/iana-corpus.json` is generated from the
 * registry's CSV and pins this table to it.
