Determine Cloudflare PoP location by Ip

How to find where Cloudflare PoP is physically located? For instance I can see that requested is routed to 104.18.31.244. And multiple Ip services in the internet says that it’s US. Same for 104.16.118.30

However I know that it’s London or Dublin. I would like to know exactly. Is there any way to find accurate location of Cloudflare Ip address.

Thanks

Hi @Tonyk1,

Cloudflare is an anycast network, which means the same IP addresses can be routed to many different servers physically.

The way to check where your request is going to is using /cdn-cgi/trace and seeing what colo is listed.

For example go to https://cloudflare.com/cdn-cgi/trace and see where your request for the Cloudflare website is going. The POPs are named based on the nearest international airport.
