Are there any drwabacks of using DHT with torrent downloads. thanks?

Question

I am looking for detailed answers that i can use in a heavy argument.

Answer 1

If you are using a private or semi-private one it is preferred that DHT  is disabled and you'll find that it will not be allowed even if you try to enable it. One reason is to prevent possible access to files that aren't readily available elsewhere.

You will also find that some ISP's modems tend to choke if DHT is enabled.

If the tracker goes down then by all means enable it if you can in order to finish the download/upload.

Sorry for being sketchy but at least you have something to go on.
