Follow-up Comment #1, bug #52503 (project wget):

Naively, it seems like wget should do what browsers do, which is, I believe,
trying all addresses.

Actually, current browsers use the "Happy Eyeballs" algorithm, doing a
non-blocking connection start on one IPv4 address and simultaneously on one
IPv6 address, and then using the connection that responds first, as this
prevents long waits in the non-uncommon case where the host has an IPv6
address, the browser has IPv6 service, but some transit network doesn't carry
IPv6, i.e., it appears that one can connect with IPv6, but any attempt is
