Editing FidoNet (section)

===Geographical structure===
FidoNet is politically organized into a tree structure, with different parts of the tree electing their respective coordinators. The FidoNet hierarchy consists of ''zones'', ''regions'', ''networks'', ''nodes'' and ''points'' broken down more-or-less geographically.

The highest level is the zone, which is largely continent-based:
* Zone 1 is the [[United States]] and [[Canada]]
* Zone 2 is Europe, Former [[Soviet Union]] countries, and Israel
* Zone 3 is [[Australasia]]
* Zone 4 is [[Latin America]] (except [[Puerto Rico]])
* Zone 5 was [[Africa]]
* Zone 6 was Asia, Israel and the Asian parts of Russia, (which are listed in Zone 2). On 26 July 2007 zone 6 was removed, and all remaining nodes were moved to zone 3.<ref>{{Citation | last = Shenkenberger | first = Carol | editor-last = Felten  | editor-first = Björn | date =  26 July 2007 | publication-date = 30 July 2007 | title = Removal of Zone 6 | periodical = FidoNews | volume =24 | issue= 31 | page = 2 | url = http://www.fidotel.com/public/fidonews/archive/2007/FIDO2431.htm | access-date = 2010-10-08 | quote =With sadness I have removed the last entry for Zone6 as of this writing.

Each zone is broken down into regions, which are broken down into nets, which consist of individual nodes.  Zones 7-4095 are used for ''othernets''; groupings of nodes that use Fido-compatible software to carry their own independent message areas without being in any way controlled by FidoNet's political structure. Using un-used zone numbers would ensure that each network would have a unique set of addresses, avoiding potential routing conflicts and ambiguities for systems that belonged to more than one network.
