Description
When a hostname resolves to multiple IP addresses, the Happy Eyeballs algorithm for connection establishment uses multiple async connection attempts in order to establish a working connection more quickly. This is essentially a faster version of the logic in MultihomeSocketConnector. Among other benefits, it solves the issues with IPv6 brokenness that can occur when a hostname resolves to both IPv4 and IPv6 addresses.
