The nntp URL scheme is an alternative method of referencing news articles, useful for specifying news articles from NNTP servers (RFC 977).
A nntp URL take the form:
where <host> and <port> are as described in Section 3.1. If :<port> is omitted, the port defaults to 119.
The <newsgroup-name> is the name of the group, while the <article- number> is the numeric id of the article within that newsgroup.
Note that while nntp: URLs specify a unique location for the article resource, most NNTP servers currently on the Internet today are configured only to allow access from local clients, and thus nntp URLs do not designate globally accessible resources. Thus, the news: form of URL is preferred as a way of identifying news articles.
