Anyone notice strange announcements for 174.128.31.0/24

At some point 3130 announced these prefixes, and is now prepending other
ASes to them.  Pretty Good BGP (and hence the IAR) sees them as prefix
hijacks.  If you'd like to see the entire list of prefixes, check out:
http://iar.cs.unm.edu/search.php and enter in 3130 as the "Victim AS"
