About CheckWhatIsMyIP
Free privacy and network tools for everyone — no accounts, no tracking, no limits.
Our Story
CheckWhatIsMyIP.com was built for one reason: most people have no idea what information their internet connection reveals about them. Every website you visit can see your IP address, your approximate location, your internet provider, and whether you are using a VPN. We built free tools to make this information visible and understandable to everyone — not just network professionals.
Our tools are used by privacy enthusiasts, IT professionals, students, gamers, remote workers, and anyone who wants to understand and protect their digital footprint.
What Makes Us Different
No Lead Generation Forms
Unlike competitors like whatismyipaddress.com, we don't force you to fill out forms or sign up for newsletters. You get instant results without giving up your email address.
No Selling Your Data
We don't sell your data to advertisers or third-party data brokers. Your privacy is not a product we monetize.
Pure Client-Side Tools
Most of our tools run entirely in your browser. Nothing is logged on our servers. Your IP lookups, fingerprint tests, and VPN checks stay private.

Our Mission
We believe everyone deserves to understand their digital footprint. CheckWhatIsMyIP.com provides free, instant, and accurate tools to help you see what information your internet connection reveals about you — and how to protect your privacy online.
Our Tools
Everything you need to understand and protect your online presence
What Is My IP
Instantly see your public IP address, city, country, ISP, timezone, and coordinates. Complete with a Google Maps visualization of your approximate location.
The tool automatically detects whether you're using IPv4 or IPv6 and runs security checks to detect VPN, proxy, and Tor usage.
IP Address Lookup
Look up any IP address to find its geolocation, ISP, organization, ASN, and more. Supports both IPv4 and IPv6 addresses.
Perfect for network administrators, security researchers, and anyone investigating suspicious IP addresses.
VPN Leak Test
Check if your VPN is actually hiding your IP. Our WebRTC leak detector finds leaks that other tools miss.
Tests for DNS leaks, IPv6 leaks, and WebRTC leaks that can expose your real IP address even when your VPN is connected.
Browser Fingerprint
See everything your browser reveals about you — OS, screen size, plugins, canvas fingerprint, and your uniqueness score.
Learn how websites track you even without cookies using advanced fingerprinting techniques.
DNS Lookup
Query DNS records for any domain. View A, AAAA, MX, CNAME, TXT, and NS records in a clean interface.
Essential for troubleshooting email delivery issues, verifying domain configurations, and investigating domain ownership.
Port Checker
Check if a specific port is open on any IP address. Test common ports like HTTP, HTTPS, SSH, FTP, and more.
Useful for diagnosing firewall issues, testing server configurations, and verifying network accessibility.
