Same here.. got a notice this morning and while it's false, I still have no response from Randy neither on this matter...
If they are going to involve our AS numbers and trigger alarms it would be nice to notify us first... especially on something as major as a prefix hijacking (potentially)

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. http://ws.arin.net/whois/?queryinput=174.128.31.0
randy lied but no packets died enough now
More seriously, this is indeed reachability research. Try emailing the AS 3130 contacts although I'd imagine Randy will see this.
