Who IP started as an IP lookup tool and grew into a platform for sharing knowledge about networking, security, and privacy. Free, no sign-up, no tracking.
IP Lookup Tool
Auto IP Detection
Your current public IP and full geolocation details appear automatically when you open the page — no input needed.
Look Up Any IP
Enter any IPv4 address to instantly retrieve its country, city, timezone, ISP, and more.
Private IP & VPN Detection
RFC 1918 private addresses are handled locally — nothing sent to any server. VPN, proxy, and data center IPs are flagged automatically.
Interactive Map
Results include an OpenStreetMap view of the IP's location with zoom and pan for a clear visual reference.
Knowledge Base
Beyond the tool, Who IP publishes articles on networking and security to help you understand what's happening behind the IP.
Networking Fundamentals
TCP/IP, NAT, DHCP, IPv4 vs IPv6, public vs private IP — building a solid foundation for understanding how networks work.
DNS
How DNS works, the privacy benefits of DNS over HTTPS, and what DNS leaks reveal about your browsing habits.
Security
VPN vs proxy, how to protect your IP address, and practical guidance on common network security threats.
Privacy
What websites can see from your IP, your digital footprint, and how to make more informed privacy choices.
No tracking, no data collection, no history stored. Queries disappear when you leave.
