What is the What is my IP? & WHOIS Lookup?
Shows the public IP address your connection presents to the internet, along with the ISP/organization and approximate location associated with it.
How it works
The page reads the client IP that Cloudflare (or the standard X-Forwarded-For header) recorded at the network edge, then the server looks that IP up against ipinfo.io to fetch its organization, reverse-DNS hostname, city, region, and coordinates. The result is cached for an hour so repeat visits don't re-query the API.
SysAdmin & security use cases
- Confirming a VPN or proxy is actually changing your visible public IP
- Looking up which ISP or hosting provider an IP address belongs to
- Checking what city or region a connection appears to route through
- Grabbing your current IP quickly to add it to an allowlist or firewall rule
