How Does IP Detection Work?
An Internet Protocol (IP) address is a unique numerical identifier assigned to every device connected to a computer network that uses the Internet Protocol for communication. Whenever you visit a website or send data across the web, your device transmits packets stamped with your public IP address so remote servers know where to return responses.
Our tool inspects the incoming socket connection at our high-speed edge gateways. By querying authoritative BGP routing tables and IP geolocation databases, we resolve your physical country, region, city, Internet Service Provider (ISP), and Autonomous System Number (ASN) in real time.
IPv4 vs. IPv6 Addresses
IPv4 uses a 32-bit address format consisting of four numbers separated by periods (e.g., 198.51.100.1), allowing for roughly 4.3 billion unique addresses.
IPv6 was introduced to eliminate IPv4 exhaustion. It uses a 128-bit hexadecimal format separated by colons (e.g., 2001:0db8:85a3::8a2e:0370:7334), providing over 340 undecillion addresses.
What Can Someone Tell from Your IP?
Your IP address reveals your approximate geographic location (country, state, and city) and your Internet Provider. It never reveals your exact home address, phone number, or personal identity without a formal subpoena served to your ISP.
Websites use your IP to enforce regional language settings, comply with licensing agreements, detect automated bot fraud, and prevent cyber attacks.
How to Hide or Change Your Public IP Address
If you wish to protect your browsing privacy or bypass geographic restrictions, you can route your web traffic through a proxy or encrypted tunnel:
- Use FreezTools Web Proxy: You can visit our free Web Proxy to surf websites anonymously with direct relay nodes and SOCKS5 egress points.
- Virtual Private Network (VPN): Encrypts all device-level traffic and assigns you an IP from a remote datacenter of your choice.
- Tor Network: Bounces your traffic across three randomized encrypted relays around the globe.
- Restarting Your Home Router: If your ISP assigns dynamic IP addresses, turning off your router for 5–10 minutes may lease a fresh IPv4 address from your ISP pool.
Frequently Asked Questions
What is my public IP address and why is it needed?▼
Your public IP address is a unique numerical label assigned to your internet connection by your Internet Service Provider (ISP). Remote websites and online servers use this address to route requested web pages, streaming media, and files back to your device.
How does FreezTools detect my IP address?▼
FreezTools detects your public IP at our high-performance edge server gateway upon socket connection. We query authoritative BGP routing registries and IP geolocation databases to resolve your approximate city, country, ISP, and Autonomous System Number (ASN) without recording your identity.
Can someone find my physical street address from my IP?▼
No. IP geolocation only provides approximate geographic coordinates down to the city or metropolitan region. It does not disclose your exact street address, house number, or personal identity without a formal legal warrant issued to your ISP.
How can I hide or change my IP address?▼
You can disguise your IP address by using our free Web Proxy tool, connecting through a Virtual Private Network (VPN), or using the Tor browser. These tools tunnel your internet traffic through external servers, presenting their IP address instead of yours.
How can I check my IP via terminal (cURL or CLI)?▼
You can query your IP directly from any terminal using `curl -s https://freeztools.com/api/my-ip` for plain text, or `curl -s https://freeztools.com/api/my-ip/json` for full JSON network details.
