This is based on last four year's data(2007-2010)collected from more than 120 peers around the world. Today it may be not announced anymore, but it used to be announced by the four ASNs simultaneously. I just checked the detailed info about this prefix, here it is about the prefix: 198.32.64.0/24 (ASN: average peers announcing this prefix:existing period:total appearing days: MOAS period: total appearing days) 4555:4.94:20080318-20080506:50:20080318-20080506:50 9584:3.07:20080402-20080513:42:20080402-20080513:42 20144:79.44:20070101-20080501:487:20071215-20080501:138 42909:26.39:20071215-20080515:152:20071215-20080513:150 > MY source data > Perhaps I'm misunderstanding the original question, but the assertion that > anybody is hijacking that particular prefix seems false. > This needs to do further analysis to confirm if it was hijacked Yaoqing > > Joe
