I'm not entirely certain what is going on but has anyone noticed some
strange announcements for 174.128.31.0/24? 

I received a hijack notice that my AS (AS11708) was announcing the above
IP range.  I verified that I was not when I started noticing some
strange announcements for that range.  Around 10 Am CST AS11911 was
announcing it  (AS_PATH: 1239 2914 3130 11911) then around 11:30 AM CST
I observed AS12083 announcing it (AS_PATH: 1239 2914 3130 12083). 

Interestingly enough, ARIN indicates this is a part of range they have
assigned for reachability testing.
