NNTP over SSL uses which port number?

Explanation:
NNTP over SSL uses port 563. This is the standard port assigned for the secure version of the Network News Transfer Protocol, known as NNTPS. Using this dedicated port helps ensure encrypted NNTP traffic is handled separately from plain, unencrypted NNTP. In practice, clients and servers enable SSL/TLS and connect to this port to guarantee communication remains private. While some deployments may run services on nonstandard ports, 563 is the recognized default for NNTP over SSL.
