Detailed Description

Reusable socket builder for address and port.

Warning: The behavior of sockets built with this builder is inconsistent across platforms

Linux: The kernel handles load balancing, and multiple sockets can receive connections

Darwin: No load balancing, only the last socket can receive connections

Windows: No load balancing, only the first socket can receive connections
