My IP Address - Find Your Public IPv4 & IPv6 Free

An IP (Internet Protocol) address is a unique numerical identifier assigned to every device connected to the internet. It allows devices to communicate and locate each other on the network, similar to how a postal address identifies your home. Every time you visit a website, your IP address is included in the request.

IPv4 uses 32-bit addresses (like 192.168.1.1) and supports about 4.3 billion unique addresses-we've run out. IPv6 uses 128-bit addresses (like 2001:db8::1) and supports virtually unlimited addresses. IPv6 was created because the world is running out of IPv4 addresses. Most internet traffic still uses IPv4.

Usually not. Most home internet connections use dynamic IP addresses that change periodically-when you restart your router or after your ISP's lease period expires. Businesses often pay for static IP addresses that remain constant. Check back after a router restart to see if yours changed.

No. IP geolocation can reveal your approximate location (city or region level), but not your exact physical address. Accuracy is typically within 50 kilometers. The location shown is where your ISP registered your IP block, not your home address. For privacy, you can use a VPN to mask your real IP.

Common reasons include: configuring remote access or VPNs, setting up gaming servers, troubleshooting network issues, verifying your VPN is working correctly, whitelisting your IP for server access, or checking if your ISP has changed your IP address.

Your public IP is the address visible to the internet, assigned by your ISP. Your private IP (like 192.168.x.x or 10.x.x.x) is used only within your local network. All devices on your home WiFi share the same public IP but have different private IPs. This tool shows your public IP.

You can hide your IP using a VPN (Virtual Private Network), which routes your traffic through a server in another location. Other options include using the Tor browser or a proxy server. Each method has different trade-offs for speed, security, and privacy. A VPN is the most common choice.

IP geolocation databases estimate location based on where your ISP registered your IP block. This can be inaccurate for mobile connections (may show carrier's hub city), ISPs serving large regions, or if the database hasn't been updated recently. The location shown is approximate, not exact.

ISP stands for Internet Service Provider-the company that provides your internet connection (like Comcast, AT&T, Vodafone, Spectrum). Your ISP assigns your public IP address and routes your internet traffic. The ISP shown here is the company that owns your IP address block.

ASN (Autonomous System Number) is a unique identifier assigned to networks on the internet. Each ISP and large organization has their own ASN-it's like a network's license plate. AS7922 is Comcast, AS15169 is Google. ASNs help route traffic between different networks globally.

IPv6 detection depends on your ISP and network configuration. Many ISPs still primarily use IPv4. If you see 'Not Detected,' your network connection came in over IPv4 only. This is normal-IPv6 adoption is still growing. You can ask your ISP about IPv6 availability.

No. We detect your IP address in real-time when you load this page, but we do not log, store, or track IP addresses. Your data exists only in your browser session. We have no record of what IP addresses have visited this tool.

Yes! We offer a free API at /api/v1/what-is-my-ip. No API key required. The response includes all data fields in JSON format. Check our API documentation at /api/docs for usage examples and rate limits.

CIDR (Classless Inter-Domain Routing) shows the IP block your address belongs to. For example, '203.0.113.0/24' means 256 addresses from 203.0.113.0 to 203.0.113.255. The /24 indicates block size. This shows the range of IPs your ISP controls for your area.
