Mainline DHT unspecified entry in bencoded dictionary
I have found an entry in a bencoded dictionary in DHT traffic, generated by BitTorrent, which I do not understand, nor can find anything about in the DHT specification at [http://bittorrent.org/beps/bep_0005.html][1].

Example of packet query and response with wireshark:

    query = {"a":{"id":".=...4...R..%..s~..;"}, "q":"ping", "t":"..oo", "v":"UThK", "y":"q"}
    response = {"r":{"id":"..=..x......o....w/%"}, "t":"..oo", "v":"UT..", "y":"r"}
full hex dump can be found here: [http://pastebin.com/SMB4f8LR][2].

The entry in this example is the `"v":"UThK"` in the query and `"v":"UT.."` in the response.
What is its purpose?
