Thanks for the update!
Sometimes connects to apache2-sith.crew.dreamhost.com
On my android phone Davdroid sometimes connects to apache2-sith.crew.dreamhost.com:80 ?
Anyone know why?
This might be coincidence, but apache2-sith.crew.dreamhost.com resolves to 18.104.22.168 which incidentally is the IP where (among others) the ical4j website is hosted (http://wiki.modularity.net.au/ical4j/index.php?title=Main_Page). Do you have details about the exact URL it connects to?
I don’t have the full URL, only the host - I use “NoRoot Firewall” app to check what happen on my network phone.
I don’t see Wiki URL in the app code - just http://ical4j.sourceforge.net/ that redirects to wiki - but I don’t see where app try to connect to it.
iCal4j might check for time zone updates, see http://wiki.modularity.net.au/ical4j/index.php?title=Timezones#TzUrl
For details, and to verify that no personal data are transmitted, see TimeZoneRegistryImpl:
The URLs can be found in the timezone definitions, for instance http://sourceforge.net/p/ical4j/ical4j/ci/default/tree/src/main/resources/zoneinfo/Africa/Abidjan.ics. The timezone URL for this time zone definition is http://tzurl.org/zoneinfo/Africa/Abidjan, and tzurl.org resolves to 22.214.171.124 (apache2-dap.parry.dreamhost.com).
Thank you for all these information
