Yes, it's ip address.

What kind of ip address? Do you understand what it points to? You will never be able to connect to 0.0.0.0.

> What kind of ip address? Do you understand what it points to?

I do not understand. It's new for me. How to know this ip address?

You probably want to connect to 127.0.0.1, usually one of the addresses associated with the system's loopback device.

Since you listen to "any address" this one should be one of them.

0.0.0.0 is sometimes used to mean "any address" in the context of listening on a server socket or binding a receiving UDP socket. It is never used as an address for connecting to a server.

Cheers,
