That prefix does not show on the HTTP version http://www.team-ymru.org/Services/Bogons/fullbogons-ipv4.txt (# last 
updated 1371214084 (Fri Jun 14 12:48:04 2013 GMT).

It appears this prefix was allocated by ARIN a couple weeks ago.

I reported the mismatch between the BGP and HTTP feeds to support@cymru, but have not received a response yet.  You may 
need to filter the announcement out from Team Cymru until they figure out why the BGP feed is not updated.
