Torrent Trackers Explanation Needed

[Elesker]

I have been googling like a mad man but I couldn't find anything.

 

I'm trying to make a list of working trackers for myself but I got confused do to all the differences

 

for example this fake tracker:

 

http://123.45.76.891:9090/announce.php

 

some have UDP instead of http, why is this?

 

so I after the IP comes the port. but is this necessary?

 

some don't even have announce.php or only announce , this gives me the idea its not needed or is it in some-way 'scratches-head' ?

 

Thank you in advance.

different tracker protocol

so I after the IP comes the port. but is this necessary?

In all cases EXCEPT when the tracker is http on port 80 or https on port 443

some don't even have announce.php or only announce , this gives me the idea its not needed or is it in some-way 'scratches-head' ?

If the tracker for a given site gives you an address with announce.php include the .php

And as a heads up, creating a tracker list to add to every torrent you load needlessly puts excessive strain on trackers that you do add to your list
