Is a machine at foo on the net?
These questions belong in news.config (if anywhere), but in fact your best bet is usually to phone somebody at foo to find out. If you don’t know anybody at foo you can always try calling and asking for the comp center. Also, see the newsgroup comp.mail.maps where maps of USENET and the uucp network are posted regularly. If you have access to telnet, connect to nic.ddn.mil and try the whois command.
