I am interested to know if there is some source of this info anywhere - and if possible which resellers link to which providers.
It’s a long shot it know, but thought I would ask.
I am using an IPTV service and want to find a backup service that is using a different provider and not reselling the same service (and therefore not providing any backup in case of iptv failure or slow connection quality)
Is it all trial and error?
Use iptv smarter on Mac. It will tell you what the main server address is. For example, nitro has nitro.ltd and limitless has lltv.xyz. Get many trials as you can, login in with xc the resellers provided and see what their main server addresses are
