WhatIsMy-IPAddress

Whatismy-IPAddress reveals what the web knows about your connection. It's a free, independent toolkit that goes far beyond a basic IP lookup — combining network diagnostics, privacy leak detection, and security checks in one place, with no signup required. Core IP & Fingerprint Info: Instantly see your public IPv4 and IPv6 address, precise location, ISP, ASN, hostname, connection type, timezone, and coordinates — plus a full browser fingerprint report covering user agent, OS, screen resolution, GPU renderer, WebGL parameters, installed fonts, media codecs, CPU cores, device memory, and more. Privacy & Leak Testing: Run a DNS leak test, WebRTC leak test, and IPv6 leak test to see if your VPN is truly private. Check whether you're using a VPN, proxy, or Tor exit node, see if you're being tracked by ad trackers, and get a data broker exposure report showing whether your ISP is selling your browsing data. Network Tools: Free subnet calculator (CIDR/IP network tool), WHOIS lookup to see who owns any IP or domain, open port scanner for firewall/RDP security checks, IP blacklist checker to see if your IP is flagged for abuse, and an accurate internet speed test. Security Checks: SPF, DKIM & DMARC checker for email domain security, password breach checker (is my password pwned), and email breach checker to see if your email has appeared on the dark web. Guides & Comparisons: In-depth VPN comparisons, VPN vs. proxy explainers, and a privacy glossary covering VPN, DNS, and IP address terminology. Built and maintained by an independent developer, whatismy-ipaddress.com is the go-to resource for anyone who wants to understand — and control — what the internet knows about them.
