Zone.dat
From ASSS Wiki
Zone.dat format
For each zone an entry like this must exist.
The last field indicates that Continuum will not warn you are entering a non-SSC zone. This is changed to 1 if you tick the box do not warn me again in Continuum. The unknown field often seems to contain a dns name for some zones such as "server.trenchwars.org" for Trench Wars. <Warn non-SSC zone> value is ignored by Continuum if the zone is an SSC zone.
<Zone name>,<Zone ip>,<Zone port>,<unknown dns (can be left blank)>,<Warn non-SSC zone> #<description>
Example:
SSCU Trench Wars,66.36.241.110,5400,server.trenchwars.org,0 #SSCU Trench Wars - Sysops: DoCk> and PriitK - http://www.trenchwars.org ss://server.trenchwars.org
Tips and Tricks
In the zone description you can prefix URLs with a name in brackets like so:
(Zone Website)http://zone.website/
Then in the "Web Links & News" menu you can name your links.
