What is an IP Address and How Does Network Geolocation Work?
An Internet Protocol (IP) address is a unique numerical label assigned to every device connected to a computer network. The internet currently operates across two primary addressing architectures: IPv4 (32-bit dotted-decimal addresses like 8.8.8.8) with approximately 4.3 billion total addresses, and the modern IPv6 (128-bit hexadecimal addresses like 2001:4860:4860::8888) designed to supply virtually limitless address space for billions of connected devices worldwide.
Your public IP address identifies your connection endpoint to websites, CDNs, and web services. When you visit a website, your ISP routes your traffic through global Border Gateway Protocol (BGP) Autonomous System Networks (ASNs). Network diagnostic registries cross-reference your ASN and IP prefix to determine approximate geographic location (country, region, city, and approximate latitude/longitude coordinates).
LocalDevTools provides deep client-side network diagnostics: instant public IPv4 and IPv6 detection, ISP organization name, autonomous system routing, and an active WebRTC Local IP Leak Test that audits whether browser real-time streaming interfaces inadvertently leak your internal home or office router LAN addresses (192.168.x.x or 10.x.x.x). None of your queries or IP addresses are stored on our servers.
How to Use This IP Address & Network Inspector
- Automatic detection: As soon as the page loads, LocalDevTools detects and presents your external public IP address, ISP provider, and approximate city/country.
- Query any custom IP or domain: Enter any IPv4 address (e.g.
1.1.1.1or8.8.8.8), IPv6 address, or domain name in the search bar and click Lookup IP. - Use one-click IPv4 presets: Click any of the quick preset buttons (Google IPv4, Cloudflare IPv4, OpenDNS IPv4, Quad9 IPv4) to inspect authoritative network telemetry.
- Audit WebRTC security: Check the WebRTC status badge below the main IP card to confirm that your internal private LAN IP is completely shielded.
Frequently Asked Questions (FAQ)
Does this tool support both IPv4 and IPv6 addresses? ↓
Yes, 100%! LocalDevTools fully supports both IPv4 (standard 32-bit addresses like 8.8.8.8) and IPv6 (128-bit addresses like 2606:4700:4700::1111). You can inspect your active public IPv4 connection or query any external IPv4 or IPv6 address at any time.
What is a WebRTC IP leak and why is it dangerous? ↓
WebRTC (Web Real-Time Communication) is the browser technology powering voice, video, and P2P data streaming. Sometimes, WebRTC STUN candidate queries bypass active VPN tunnels and reveal your true private LAN IP address or ISP connection. Our tool audits this vulnerability automatically and flags any candidate exposures.
How accurate is IP-based geolocation? ↓
IP geolocation provides country and regional accuracy of 95%–99%, and city-level accuracy of approximately 80%–90%. It identifies your ISP's regional routing hub rather than your exact physical house address, protecting your personal physical privacy.
Does LocalDevTools log or track my IP address? ↓
Zero logging. LocalDevTools has no database or analytics tracking servers recording your visits or IP history. Queries are fetched directly from your browser to public HTTPS telemetry endpoints.
