IP Geolocation with Anycast IP addresses

[Sylvia2]

Hi there,

I am wondering how geolocation is working with IP addresses where anycast is used.

Anycast addresses are shared by multiple server, typically with different locations.

How is such an address assigned to a particular country/region in the Geolocation DB?

Does anybody know?

Thanks,

Sylvia

@Sylvia2,

I don't think there's any rhyme or reason for where these get placed. CloudFlare's 1.1.1.1 is currently listed in Australia, Google's 8.8.8.8 is listed in the United States, along with Quad9's 9.9.9.9.

I see the same for various public DNS at the moment, though I have had problems with them changing in the past. So I created a custom region code "CDN" in Objects -> Regions and placed any kind of generic anycast/CDN addresses that I want to communicate with. Use my custom CDN region, in addition to standard country region codes, as the destination in outbound rules.
