Thanks for clarifying this, actually I have a few more blocks with four origin ASNs that I'm not positive if they are anycast prefixes. Please help distinguish them if the provide anycast service. 27.130.0.0/16 58.147.0.0/20 58.147.0.0/17 58.147.16.0/20 58.147.64.0/20 58.147.80.0/20 58.147.96.0/20 58.147.112.0/20 61.237.224.0/20 65.61.188.0/24 69.20.95.0/24 110.164.0.0/16 110.164.48.0/20 110.164.64.0/20 110.164.80.0/20 110.164.176.0/20 112.142.0.0/16 112.143.0.0/16 180.183.0.0/16 198.32.64.0/24 198.32.136.0/24 198.32.175.0/24 202.69.136.0/21 202.99.58.0/24 202.122.116.0/24 203.119.30.0/24 204.79.195.0/24 204.79.197.0/24 206.51.38.0/24 206.223.116.0/24 207.231.241.0/24 208.67.239.0/24 222.35.0.0/18 222.35.248.0/21 222.123.0.0/16 223.204.0.0/16 223.205.0.0/16 Yaoqing On Mon, May 2, 2011 at 11:20 PM, <bmanning@vacation.karoshi.com> wrote:

I found the following prefixes are often originated by many ASNs more

five, wonder if they provide global anycast service, if so what specific service they provide?

CERNET.

as a note, this is bmanning/ep.net exchange space, no? so this could be just people leaking this into their table/global-table by mistake?
used to be. ep.net has fragmented into little bits. most of the prefixes have been transfered to the clients who were using them, the ones who are still around are outside the ARIN region and there is no clean way to move them given ARIN and other RIR policy.
This particular prefix was used as a public exchange, operated by Switch & Data. Not sure what they have done w/ it since then.
