AS13335 is the ASN this site’s list labels Cloudflare, checked 13 Oct 2026. ipinfo.fyi itself runs on Cloudflare. An address announced from AS13335 is infrastructure: CDN, DNS, Workers, or another Cloudflare service. It is not your home ISP.
Many of those prefixes are anycast. The same address can be served from many cities, so a geolocation pin is often the wrong city even when the network name is right. Sites that treat every datacenter address as a VPN will flag AS13335. That flag means “this is cloud infrastructure”, not “a VPN app is running”.
1.1.1.1 is Cloudflare’s public resolver and is announced on this network. Looking it up tells you about Cloudflare, not about the person who queried it.
Questions
Why is the location of a Cloudflare IP wrong?
Anycast addresses are announced in more than one place. Databases still have to print a single city. Disagreement there is normal.
