according to Filip, this is -NOT- supposed to be anycast. the only legal origin ASN is 4555.
these other ASNs have hijacked the prefix.
The source data above may be old, or simply wrong -- I don't see *any* AS originating that prefix right now, and I can confirm specifically AS20144 is not configured to originate it.
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
