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:
