A public news server is an USENET (NNTP) site that is intentionally kept open for all IP addresses without requiring any kind of authentication. This site is especially designed for those who wish a simple and quick way to read the USENET news without needing to post an huge amount of articles. In order to keep low the number of abuses, there're various limits to the users' access rights, notably in the number of articles per day that each IP address is authorized to post (25) and in the amount of connections that each client is able to establish (600) in a day before being banned. All informations about the rules that the users are enforced to strictly observe are shown in the QuickStart Guide and in the Posting Policy that all people should read before starting to use this service.
In order to protect the users' privacy, each article sent through this host to every USENET group doesn't reveal the sender's IP address. However, this information is kept in the system logs for 6 months before being deleted as enforced by the italian law. More informations about the log data retention are available in the Privacy Policy.
This site supports the SSL encrypted connections in order to increase the users' protection: all clients should enable it if their news agent supports this feature. Those who need help should read the section in the site that explain how to configure the most common newsreaders.
A detailed list of all hosts and ports that are used by the servers is available in this page.
