Description

The current implementation uses hostname to create connections. It causes two problems in a scenario where multiple addresses are bound to the same domain name.

1. Load balancing is broken because multiple `Host` may connect to the same address, and some addresses may have no connection at all.
2. It produces misleading log messages because the address in the host label may not be the one the host is actually connected to.
