What Is an IP Address?
An IP (Internet Protocol) address is a unique numerical identifier assigned to every device connected to the internet. It serves two primary functions: identifying the host or network interface and providing the location of the device within the network. Every time you visit a website, send an email, or stream video, your IP address is transmitted to the server you’re connecting to.
There are two versions of IP addresses in use today: IPv4 (e.g., 192.168.1.1) uses a 32-bit format with approximately 4.3 billion possible addresses, while IPv6 (e.g., 2001:0db8:85a3::8a2e:0370:7334) uses 128-bit addresses to support the growing number of internet-connected devices.
How Does IP Geolocation Work?
IP geolocation maps an IP address to a physical location using databases maintained by Regional Internet Registries (RIRs) like ARIN, RIPE, and APNIC. These databases track which IP ranges are allocated to which ISPs and organizations, and in which regions they operate. While IP geolocation is accurate at the country level (95-99%), city-level accuracy typically ranges from 50-80% depending on the IP type and database used.
Why Check Your IP Address?
- Verify your proxy is working — After connecting to a proxy server, check if your visible IP has changed to confirm the proxy is active.
- Test VPN connections — Ensure your VPN is routing traffic correctly and not leaking your real IP address.
- Debug geo-targeting — Verify that your proxy’s IP shows the correct geographic location for your target market.
- Check for IP leaks — Use alongside our Browser Fingerprint Tester to detect WebRTC leaks that could expose your real IP.
- Monitor IP reputation — Check if your IP is flagged as a proxy, VPN, or hosting IP, which can affect scraping success rates.
Understanding Proxy Detection
Websites and anti-bot systems use multiple techniques to detect proxy and VPN usage. Our tool checks for common indicators including datacenter IP ranges, known VPN/proxy provider IP blocks, and hosting provider associations. Residential proxies are significantly harder to detect because they use real ISP-assigned IP addresses. If you need proxies that bypass detection, check our Proxy Cost Calculator to compare residential proxy pricing.
IP Types Explained
- Residential IP — Assigned by an ISP to a home user. Most trusted, hardest to detect as a proxy.
- Datacenter IP — Hosted in commercial data centers. Fast but easily identified as non-residential.
- Mobile IP — Assigned by mobile carriers (4G/5G). Shared among millions of users, extremely difficult to block.
- ISP/Static Residential IP — Datacenter-hosted but registered under a real ISP. Combines speed with residential trust.
Frequently Asked Questions
Can websites see my real IP if I use a proxy?
If your proxy is configured correctly, websites will only see the proxy’s IP address. However, WebRTC leaks, DNS leaks, or misconfigured browser settings can expose your real IP. Use our Browser Fingerprint Tester to check for WebRTC leaks.
Why does my IP location show a different city?
IP geolocation is based on ISP registration data, which may not perfectly match your physical location. ISPs often register IP blocks at their headquarters or regional offices. City-level accuracy is typically 50-80%. Country-level accuracy exceeds 95%.
What’s the difference between a public and private IP?
Your public IP is what websites see when you connect to them. Your private IP (like 192.168.x.x) is used within your local network and is not visible to external servers. This tool shows your public IP address.
How often does my IP address change?
It depends on your ISP. Most residential connections use dynamic IP addresses that change periodically (every few hours to days). Business connections and servers typically have static IPs that don’t change. If you’re using a proxy, your visible IP changes with each new proxy connection.
Is it safe to share my IP address?
Your IP address is shared with every website you visit automatically. While knowing an IP alone isn’t dangerous, it can reveal your approximate location and ISP. For privacy, use a proxy or VPN to mask your real IP. Our Proxy Cost Calculator can help you find the right proxy for your budget.
