Hi Fredy, Our anycast prefixes for DNS resolver 185.222.222.0/24 2a09::/48 You can add them if someone will maintain a list. Regards, David -----Original Message----- From: NANOG <nanog-bounces@nanog.org> On Behalf Of Fredy Kuenzler Sent: Wednesday, March 20, 2019 1:13 AM To: nanog@nanog.org Subject: well-known Anycast prefixes I wonder whether anyone has ever compiled a list of well-known Anycast prefixes. Such as 1.1.1.0/24 8.8.8.0/24 9.9.9.0/24 ... Might be useful for a routing policy such as "always route hot-potato". PS. this mail is not intended to start a flame war of hot vs. cold potato routing. -- Fredy Kuenzler Init7 (Switzerland) Ltd.
