Free IP Address Tools for Developers, Sysadmins & Network Engineers
IP Tracker Tools is a collection of free networking utilities for every stage of IP and network management - from finding your public IPv4 and IPv6 to calculating subnet boundaries, checking open ports, tracing routes, and testing whether your VPN leaks your real identity.
Works Worldwide
Our free IP checker and network tools work from anywhere in the world including the United States, Canada, United Kingdom, Ireland, Germany, France, Netherlands, Belgium, Spain, Italy, Sweden, Norway, Denmark, Finland, Poland, Australia, New Zealand, United Arab Emirates, Saudi Arabia, Qatar, Kuwait, Bahrain and Oman.
No installation is required. Every tool runs in your browser over HTTPS, supports desktop, tablet, and mobile, and delivers accurate geolocation from fast global lookup servers. Privacy friendly - no signup, no account, and calculators never send your internal IP ranges to a server.

Common Uses
Practical reasons people check their IP and run network diagnostics every day:
IP Lookup Tools
The What Is My IP tool auto-detects your public IPv4 and IPv6. The IP Address Lookup shows country, city, ISP, ASN, and coordinates for any address. The IP to ISP Lookup focuses on the network operator. For batch work, Bulk IP Lookup handles 20 IPs with CSV export.
Subnet and CIDR Calculators
The Subnet Calculator computes network address, broadcast, usable host range, and host count from any CIDR - entirely in your browser. The CIDR Calculator works in both directions. The IPv6 Subnet Calculator uses JavaScript BigInt for 128-bit arithmetic.
Network Testing and Diagnostics
The Port Scanner and TCP Port Test check open ports from the internet. The Ping Test and Traceroute map latency and routing paths. The HTTP Headers tool shows response headers and your browser's User-Agent string.
Privacy and Security Verification
The VPN Leak Check auto-detects seven types of VPN leaks. The DNS Lookup and Reverse DNS Lookup help troubleshoot name resolution. The IP Blacklist Check queries 20 major DNSBLs. The IPv6 Compatibility Test scores dual-stack readiness.

Frequently Asked Questions
Answers about IP addresses, privacy, supported countries, and how our free tools work:
What can I do with these IP and network tools?
You can look up public IP details, check your own IP, query DNS and WHOIS records, test ports and reachability, run traceroute and ping checks, calculate subnets and CIDR ranges, and verify VPN or DNS leaks. Most calculators run in your browser; live lookups use public network data sources to return results.
How do I find my public IP address?
Use the checker at the top of this page, or open What Is My IP. The site shows the public IPv4 and IPv6 addresses remote servers see for your connection. That is different from the private address your router assigns on your local network.
What does an IP lookup show?
An IP lookup typically returns the ISP or organization linked to the address, ASN details when available, and an estimated location such as country, region, or city. Results come from registration and geolocation databases, so they can lag renumbers and may be wrong for VPNs, mobile networks, or shared hosting ranges.
What is the difference between a public IP and a private IP?
A public IP is routable on the internet and is what websites see. A private IP (for example 192.168.1.10 or 10.0.0.5) works only on your local network. Home and office routers use NAT so many private devices can share one public address.
What is DNS lookup used for?
DNS lookup shows how a domain name resolves to IP addresses and which records are published (such as A, AAAA, MX, CNAME, TXT, or NS). It helps diagnose website, email, and connectivity problems when a name does not resolve as expected.
What is WHOIS lookup?
WHOIS returns registration data for a domain or IP range when that data is publicly available—often registrar details, creation and expiry dates, and nameservers. Privacy redaction and registry rules mean contact fields are frequently hidden.
How do I check if a port is open?
Use the port checker or TCP/UDP port test tools and enter the host and port you want to probe. An open result means a service answered from this checker’s network path. Firewalls, rate limits, and path differences can make results differ from what you see on another network.
What is a subnet calculator used for?
A subnet calculator turns an IP address and prefix (CIDR) into network address, broadcast address, subnet mask, and usable host range. It helps plan LAN addressing, divide networks, and verify that a range fits the hosts you need.
How can I tell if my VPN is hiding my real IP?
Connect to the VPN, then check What Is My IP or run the VPN and DNS leak tests. If the visible IP, ISP, or DNS resolvers still match your home or mobile provider, traffic may be bypassing the tunnel. Leak tests check more than a single IP display alone.
How accurate is IP geolocation?
Country-level estimates are often reliable, but city and coordinates can be off by a large margin. Accuracy depends on the database, how ISPs register address blocks, mobile gateways, VPNs, and hosting ranges. Treat location fields as approximate, not as a precise physical address.
Do I need an account to use these tools?
No. The tools on this site are free to use in a browser without creating an account. Some live lookups depend on third-party APIs and may be rate-limited under heavy use.
Do you store my IP lookups?
Browser-based calculators and validators process inputs on your device. Live tools send the queried host or IP to the services needed to return a result. We do not keep a personal lookup history in the app. Hosting, security, and analytics processing are described in the Privacy Policy.
