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.

Who Uses This Tool?
From home users to enterprise teams - anyone who needs fast, accurate network information:
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 is my IP address?
Your IP address is the public number your ISP assigns to your connection. The quick checker at the top of this page detects it automatically. For full IPv4, IPv6, ISP, and location details, open the What Is My IP tool.
How do I find my public IP?
Visit this homepage or our What Is My IP page in any browser. Your public address appears within seconds. Device settings show your private local IP (such as 192.168.x.x), not the public IP websites see.
What is IPv4?
IPv4 is the classic four-part address format (for example 203.0.113.45). It supports about 4.3 billion addresses. Most home and office networks still rely on IPv4, often with NAT so multiple devices share one public address.
What is IPv6?
IPv6 is the newer 128-bit format (for example 2001:db8::1) with a vastly larger address space. Many ISPs in the US, UK, EU, Australia, and the Gulf now assign IPv6 alongside IPv4.
How do I check my IP in the USA?
Open this site from any US network - home broadband, office Wi-Fi, or mobile data. Your public IP, ISP, and approximate location appear in the checker at the top of the page. No extra setup is required.
How do I check my IP in Canada?
Canadian users can load this page from any province or territory. The IP checker detects your public IPv4 or IPv6, ISP name, and estimated region automatically in the browser.
How do I find my IP in the UK?
From England, Scotland, Wales, or Northern Ireland, use the checker on this homepage or the dedicated What Is My IP page. Results update when you switch networks or connect to a VPN.
How do I check my IP in Ireland?
Users in Ireland can check their public IP instantly here. The tool works on desktop, tablet, and mobile browsers with no signup or installation.
Does a VPN change my IP?
Yes. A VPN routes traffic through a remote server, so websites see the VPN IP instead of your home address. Use our VPN Leak Check to confirm your real IP stays hidden after connecting.
Can websites see my IP?
Yes. Every site and online service you connect to receives your public IP as part of normal traffic. It does not by itself reveal your name or exact street address.
Is my IP private?
Your public IP is visible on the internet. Private addresses (192.168.x.x, 10.x.x.x) stay on your local network and are not shown by our public IP tools.
Can my ISP change my IP?
Yes. Most residential and mobile plans use dynamic IPs from a shared pool. Your address can change when the router reboots, the DHCP lease renews, or you switch networks.
What is a dynamic IP?
A dynamic IP may change over time. It is standard for home broadband and mobile networks worldwide. Dynamic IPs work fine for everyday browsing, streaming, and email.
What is a static IP?
A static IP stays fixed until you or your ISP changes it. Businesses often use static IPs for servers, remote access, firewall rules, and API whitelisting.
Can I hide my IP?
You can mask your public IP with a VPN, proxy, or Tor. A VPN is the most practical everyday option. After connecting, use What Is My IP or our VPN Leak Check to verify the change.
Can I use IPv6?
If your ISP and router support IPv6, our tools detect and display it alongside IPv4. Run the IPv6 Compatibility Test for a full dual-stack readiness score.
How accurate is IP geolocation?
Country detection is usually very accurate. City estimates can be off by tens of miles because ISPs register blocks in hub cities, mobile carriers use shared gateways, or VPNs route traffic elsewhere.
Can I check my IP on mobile?
Yes. Open this site on iPhone, Android, or any mobile browser. The checker detects your cellular or Wi-Fi public IP the same way as on desktop.
Does this tool work worldwide?
Yes. IP Tracker Tools works from the United States, Canada, UK, Ireland, across Europe, Australia, New Zealand, the UAE, Saudi Arabia, Qatar, Kuwait, Bahrain, Oman, and other countries worldwide.
Is this tool free?
Yes. The IP checker and all 40+ network tools on this site are free. No signup, no subscription, and no payment required.
Are all IP Tracker Tools free?
Every tool on this site is free to use. Calculators and validators run in your browser. Live lookup tools query public APIs - we do not charge for access.
Do my IP lookups get logged?
Subnet calculators, validators, and converters run entirely in your browser - your internal ranges never leave your device. Live lookups (WHOIS, geolocation, port checks) send only the queried IP to the relevant API, not to us for storage.
