- TCP:
- `listen` bind to wildcard "*" -> dual stack socket
- `listen` bind to address -> socket from address type
- `connect` -> resolve using best protocol (UNSPEC), socket from address type
- UDP:
- `listen` bind to wildcard "*" -> dual stack socket
- `listen` bind to address -> socket from address type
- `put_packet`/`put_var` -> resolve using TYPE_ANY (UNSPEC), socket from address type
(to change socket type you must first call `close` it)
