Trackers, bit of n00bs question.

[Badgerboy]

Hello
Sorry if this sounds like a stupid question but what are Trackers? Why do some website, like torrentspy stress they don't host Trackers.

Does a Tracker do anymore then just provide the .torrent supplier with information regarding there file?

Like I said, sorry for being a bit dumb just trying to get my head around it

the tracker basically just holds the i.ps of everyone connected to the torrent. when ur bittorrent client connects to the tracker, the tracker gives it all the i.p's connected.
