Torrenting may sometimes be limited by Internet Service Providers (ISPs), on legal or copyright grounds.

Params	Name	Description
dn	Display Name
xt	eXact Topic	URN containing file hash
tr	address TRacker	Tracker URL

xt

xt parameter specifies the URN for a given p2p protocol.

BitTorrent info hash (BTIH)

xt=urn:btih:[ BitTorrent Info Hash ]

ED2K

xt=urn:ed2k:[ ED2K Hash ]

SHA-1

xt=urn:sha1:[ SHA-1 HASH ]

MD5

xt=urn:md5:[ MD5 Hash ]
