Each protocol handles a URN uniquely; for example, <code>xt=urn:btih:FFC7E738EAA4CD4ECF51EC6FD669C6CDE2C281A8</code> uses the btih (BitTorrent v1 protocol), so a BitTorrent client can take the hash and lookup the torrent's metadata in the BitTorrent DHT.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> In the case of DHT the client searches through a set of pre-known nodes and requests the metadata for an infohash; those nodes will make the same request to other known nodes until eventually a swarm is found and returned. </p><p>xt also allows for a group setting.
