Who can see my IP address on ip.notb.st?

Cloudflare, which runs the site, receives every request and supplies your approximate location. Two outside services see it too: ipify returns your IPv4 and IPv6 address, and ipapi.co names your provider and ASN. Our own cookieless analytics server receives the visit as well. ip.notb.st does not log or store your IP, sets no cookies and needs no account.
