That prefix does not show on the HTTP version http://www.team-ymru.org/Serv=
ices/Bogons/fullbogons-ipv4.txt (# last updated 1371214084 (Fri Jun 14 12:4=
8:04 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, bu=
t have not received a response yet.  You may need to filter the announcemen=
t out from Team Cymru until they figure out why the BGP feed is not updated=
