5.6.6.  Example


      Path: foo.isp.example/
         .foo-server/bar.isp.example?10.123.12.2/old.site.example!
         barbaz/baz.isp.example%dialup123.baz.isp.example!x

        NOTE: That article was injected into the news stream by
        baz.isp.example (complaints may be addressed to
        usenet@baz.isp.example). The injector has taken care to record
        that it got it from dialup123.baz.isp.example. "x" is the
        default tail entry, though sometimes a real userid is put there.

        The article was relayed, perhaps by UUCP, to the machine known
        in the UUCP maps database as "barbaz".

        Barbaz relayed it to old.site.example, which does not yet
        conform to this standard (hence the '!' delimiter). So one
        cannot be sure that it really came from barbaz.

        Old.site.example relayed it to a site claiming to have the IP
        address [10.123.12.2], and claiming (by using the '/' delimiter)
        to have verified that it came from old.site.example.

        [10.123.12.2] relayed it to ".foo-server" which, not being
        convinced that it truly came from [10.123.12.2], did a reverse
        lookup on the actual source and concluded it was known as
        bar.isp.example (that is not to say that [10.123.12.2] was not a
        correct IP address for bar.isp.example, but simply that that
        connection could not be substantiated by .foo-server).  Observe
        that .foo-server has now added two entries to the Path.
        ".foo-server" is a locally significant name (observe the
        presence of the '.')  within the complex site of many machines
        run by foo.isp.example, so the latter should have no problem
        recognizing .foo-server and using a '/' delimiter.  Presumably
        foo.isp.example then delivered the article to its direct
        clients.

        It appears that foo.isp.example and old.site.example decided to
        fold the line, on the grounds that it seemed to be getting a
        little too long.
