# NET100

An IPv4 unspecified address, "0.0.0.0", or an IPv6 unspecified address "::" inside a `bind()` call. This implies attempt to bind all network interfaces.

Unspecified address literals are: - `0.0.0.0` - `::` - `0:0:0:0:0:0:0:0`

## Example

    import socket

    # create an INET, STREAMing socket
    serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    # bind the socket to a public host, and a well-known port
    serversocket.bind(("0.0.0.0", 80))
    # become a server socket
    serversocket.listen(5)
