I started using bittorrent for downloading large items such as Linux ISOs, Live CDs, etc.

When I have finished downloading I normally leave it open to contribure to the bittorrent link for a bit. Until I really need my upstream bandwidth. However, I've noticed that the bittorrent tracker does not take you off the list and still references your IP for several hours to come.

In my opinion, the tracker should be responsible for keeping an up2date list of participating peers, rather than to throw a sh17 load of traffic my way? My firewall is dropping it but it still clogs my upstream connection. This doesn't use up ALL my bandwidth... but quite a bit of it. Slows me to a crawl.

I feel bad for the people on dial up who get an IP that was just used by oneone using bittorrent.
They are no doubt going to be VERY slow. They will basically be DDoS'd off their connection. Granted, they can reconnect with a new IP.. but anyone who gets that IP will be DDoS'd because the tracker is still referencing that IP as a participating peer.

I can't tell if this is a problem with just one tracker.

I'll have to do some more testing and see what I come up with.

The only way to get around this is to release the WAN ip and renew it. But whoever gets that IP next will still get a flurry of traffic on ports 6881-6889...

Anyone else notice this?
