"Happy Eyeballs" is documented in RFC6555 as the recommended practice

In this implementation, we partition the addresses by family, and

make the first connection attempt to whichever address was

returned first by ``getaddrinfo``. If that connection fails or
|
|
times out, we begin a connection in parallel to the first address

of the other family. If there are additional failures we retry

|
with other addresses, keeping one connection attempt per family

in flight at a time.
