What Is an IP Address?
Your IP address is a unique number assigned to your device by your Internet Service Provider. It's how the internet knows where to send the websites, videos, and messages you request — like a return address on an envelope.
Every device that connects to the internet — your phone, laptop, smart fridge — gets one. When you visit a website, your browser sends your IP to the server so it knows where to deliver the response.

How Does IP Geolocation Work?
IP geolocation maps an IP address to a physical location by cross-referencing databases maintained by regional internet registries (ARIN, RIPE, APNIC), ISPs, and commercial providers like MaxMind and DB-IP.
The data sources include WHOIS records (who owns this IP block), routing tables (BGP), latency measurements, and user-contributed corrections. Combined, these give a probabilistic estimate of where a device is connecting from.
Country-level accuracy exceeds 99%. City-level accuracy typically falls between 50–80% depending on the region and ISP.
MyIPHelp cross-references two databases (MaxMind GeoLite2 + DB-IP Lite) and surfaces the agreement — when both sources agree, confidence is high; when they disagree, you'll see both values so you can judge.
Public vs. Private IPs
A public IP is what the internet sees — the address assigned to your router by your ISP. A private IP is what devices on your home network use to talk to each other (typically 192.168.x.x, 10.x.x.x, or 172.16–31.x.x).
Your router does the translation — that's NAT, Network Address Translation. To find both, you'll use different commands:
# Windows $ ipconfig # macOS / Linux $ ifconfig $ ip addr
The public IP at the top of this page is what every website you visit can see. The private IPs your router uses internally stay private to your network.
IPv4 vs. IPv6
IPv4 uses 32-bit addresses like 8.8.8.8, allowing roughly 4.3 billion unique addresses — a number the internet has already outgrown. IPv6 uses 128-bit addresses like 2001:0db8::1, supporting a practically unlimited count (340 undecillion, if you must).
About 43% of global internet traffic now uses IPv6, with adoption highest in India, the US, and Germany. Most modern devices and ISPs handle both — dual-stack — automatically.
How to Protect Your IP
Your IP isn't a secret — every website you visit can see it — but you may want to mask it for privacy or to bypass region restrictions. Common options:
- → VPN — routes all your traffic through a server in another location. Effective and fast. Look for no-log providers based in privacy-friendly jurisdictions.
- → Tor — bounces your traffic through several volunteer-run relays. Maximum anonymity, lowest speed.
- → Proxy — like a VPN but typically per-app and without encryption. Useful for specific tools, not whole-system privacy.
To check whether your VPN is actually masking you, reload this page and confirm the IP and city match the VPN's exit node — not your real location.
What Is an IP Address?
Your IP address is a unique number assigned to your device by your Internet Service Provider. It works like a return address for internet traffic — every time you visit a website, your IP tells that site where to send data back. Without it, nothing on the internet would know how to reach you.
There are two formats: IPv4 addresses (like 192.168.1.1) use four groups of numbers and have been the standard since the 1980s. IPv6 addresses (like 2001:0db8:85a3::8a2e:0370:7334) are longer and were created because the world is running out of IPv4 addresses. Most networks now support both.
Your public IP address — the one websites see — can reveal your approximate location, your ISP, and whether you’re connecting from a residential network, a data center, or through a VPN. Tools like our IP geolocation lookup cross-reference multiple databases to map these details.
How Does IP Geolocation Work?
IP geolocation determines a device’s approximate physical location based on its IP address. Providers like MaxMind and DB-IP maintain large databases that map IP ranges to geographic coordinates, ISPs, and autonomous systems. These databases are built from registry records (ARIN, RIPE, APNIC), network routing data, and direct contributions from ISPs.
Accuracy varies by what you’re looking for. Country-level detection is correct over 99% of the time. City-level accuracy typically falls between 50–80%, depending on the region and ISP. Rural areas and mobile networks tend to be less precise than urban broadband connections.
My IP Help cross-references MaxMind GeoLite2 and DB-IP Lite to improve reliability. When one source lacks data — such as a postal code or timezone — the other often fills the gap. You can learn more about our methodology on the data sources page.
Public vs Private IP Addresses
Every device connected to the internet has two types of IP address. Your public IP is the address the outside world sees. It’s assigned by your ISP and shared by all devices on your home or office network through a router. Your private IP (usually starting with 192.168.x.x or 10.x.x.x) is used only within your local network and is invisible to websites.
When you use this page, we detect your public IP — the one your router presents to the internet. If you’re connected through a VPN or proxy, you’ll see the VPN server’s IP instead of your ISP’s. You can verify this by checking your IP with and without your VPN enabled using our IP lookup tool.
To find your private IP address on your local network, check your device’s network settings. On Windows, run ipconfig in Command Prompt. On Mac or Linux, use ifconfig or ip addr in Terminal.
How to Protect Your IP Address
Your IP address alone cannot reveal your exact street address or identity, but it does expose your general location and ISP. Combined with other data, it can be used for targeted advertising, content restrictions, or in some cases, network attacks.
A few practical steps to limit your IP exposure: use a reputable VPN service to mask your real IP behind the VPN server’s address. Enable your browser’s DNS-over-HTTPS setting to prevent your ISP from logging your browsing activity. And review which apps and services have access to your network information.
You can use our HTTP header checker to see exactly what information your browser sends with every request, or run an SSL certificate check to verify that sites you visit are encrypting your connection properly.
Why Check Your IP Address?
Knowing your public IP is useful in several everyday situations. If you’re setting up a firewall or remote access, you need your exact public IP to create allow-list rules. If you manage an email server, checking your IP against blacklists helps diagnose delivery problems before they affect your users.
For anyone using a VPN or proxy, a quick IP check confirms whether your traffic is actually being routed through the intended server. If your real IP leaks through, your location and ISP remain visible to every site you visit.
Network professionals use IP lookups for troubleshooting and auditing — identifying which ISP or autonomous system a problematic IP belongs to, running DNS lookups to verify records, or using visual traceroute to map the path packets take across the internet.
Frequently Asked Questions
How do I find my public IP address?
Visit any IP lookup tool like MyIPHelp and your public IP address is displayed automatically. No signup or software is needed. You can also run curl ifconfig.me from the command line.
What can someone do with my IP address?
An IP address reveals your approximate city, ISP name, and connection type. It cannot reveal your street address, name, or phone number. Websites use it for content localization and fraud detection.
Is my IP address safe to share?
Your IP is already visible to every website you visit. Sharing it does not expose personal details beyond your approximate location and ISP. For extra privacy, use a VPN to mask your real IP.
What is the difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses (like 192.168.1.1) with about 4.3 billion combinations. IPv6 uses 128-bit addresses (like 2001:0db8::1) supporting a practically unlimited number. About 43% of global internet traffic now uses IPv6.
How accurate is IP geolocation?
Country-level accuracy exceeds 99% according to MaxMind. City-level accuracy ranges from 20% to 75% depending on region. VPN users, mobile networks, and corporate proxies can reduce accuracy.
