Information about Usenet hierarchies

If you know a hierarchy which is not listed in these pages or if you have more up-to-date information about an existing hierarchy, please send a mail to usenet-config@isc.org or post to news.admin.hierarchies so that these pages can be updated.

A text-only version of that page can also be retrieved for a control access file, PGP keys and a checkgroups. Full files are also available.
