Which port number is assigned to NNTP (Network News Protocol)?

Explanation:
The main idea here is identifying the standard port used by Network News Protocol communications. NNTP operates on port 119 for its plain, unencrypted connections. This is the traditional, default port that clients and servers use to exchange NNTP traffic. The other ports serve different services: 110 is for POP3 email retrieval, 563 is the secure version of NNTP (NNTP over TLS), and 123 is for NTP (time synchronization). So, the correct port for NNTP in its standard form is 119.
