What is an IP address?
An IP address is a unique number that identifies a computer or device on a network. It allows information to route to and from your devices and reach the correct place on a network. Without IP addresses, the Internet wouldn't function because routers, servers, and websites rely on these numerical labels to exchange data securely.
When learning about IP addresses, it helps to understand the difference between public vs private IP addresses. A private IP address is used inside your home or office network to let devices like computers, printers, and phones communicate with each other. A public IP address is what your Internet service provider assigns to your network so it can be recognized on the wider Internet. In short, private IPs keep devices connected locally, while public IPs make sure your network can send and receive data online, a distinction defined in RFC 1918.
How the IP lookup tool works
An IP lookup retrieves information about an IP address, including its location, hostname, and network details. It helps to diagnose network issues, track malicious activities, or maintain online privacy.
To use the IP lookup tool:
- Enter any IPv4 or IPv6 address into the search field at the top of the page.
- Click the Lookup button.
- View the details the tool returns, including city, region, postal code, country, ISP, and time zone.
Your IP will automatically be filled into the tool when you first visit the page. To look up another IP, simply replace it with any IPv4 or IPv6 you want to investigate.
What information can you find with the IP address lookup?
The search results provide a detailed set of information about the IP address and its associated network, including:
- City
- State/Region
- Postal/Zip Code
- Country
- Internet Service Provider (ISP)
- Time Zone
- Autonomous System Number (ASN), when available, which identifies the network operator responsible for the IP
How accurate is IP geolocation?
IP geolocation isn't 100% accurate. Location data is estimated using multiple third-party databases from providers like IP2Location and IPData. Accuracy may vary based on how an ISP registers its IP blocks, use of VPNs or proxies, cell networks, or anonymous browsers like Tor.
In many cases, IP geolocation results are the most accurate at the country level, moderately accurate at the region level, and typically least accurate at the city level.
Some IP ranges, especially mobile carriers and satellite networks, regularly rotate or centralize routing, which further reduces accuracy for city-level results.
Why use an IP address lookup?
Though looking up an IP address might sound like a concerning concept, it actually has many benefits for users when handled responsibly.
Here are some common reasons to perform an IP lookup:
- Identifying suspicious activity or spam sources
- Discovering your public IP and ISP
- Verifying location accuracy for VPNs or proxies
- Targeting ads or content by region
- Troubleshooting network issues, such as inconsistent geolocation that may affect website logins or streaming access
Used properly, IP lookups help improve online safety, diagnose technical issues, and verify location-based services. These use cases ultimately support a better experience for website owners, IT teams, cybersecurity professionals, and everyday users who want greater clarity about how their IP appears online.
Limitations of the IP tool
While the IP address lookup can provide valuable information, it does have limitations that users should understand before relying on the results.
- IP location is approximate, not accurate. The lookup only provides a general location, which may not always be accurate due to how IP blocks are registered and maintained by ISPs.
- Dynamic IPs may change frequently. Some ISPs use dynamic IPs, meaning your IP changes frequently. This makes it challenging to track down a specific user or consistently associate activity with the same address over time.
- VPNs and proxies obscure true locations. If you're using a VPN, your IP address will likely indicate a different location because the request appears to originate from the VPN server's IP block rather than your own.
- Some users may have privacy concerns. The lookup can reveal personal information, like your general location and Internet service provider.
Looking up an IP with this tool provides many benefits, but be aware of the limitations as well. You may need to use another WhatIsMyIP tool to get the information you're looking for, such as the WHOIS lookup for ownership details or a DNS tool for hostname information.
Reporting IP abuse
If you’re looking up an IP address because you believe you've become a victim of IP abuse, don't act immediately. It’s important to report the IP abuse rather than attempting to handle it yourself. Don’t assume that the owner of the IP address is the person behind the abuse; IPs often reflect networks, not individuals.
Instead, perform an IP WHOIS Lookup to get further IP address details, including abuse contact information for IP address owners. You can block the offending IP address. Then, file a complaint with the authorities or your Internet service provider and allow them to handle the situation.
Most major hosting providers, including Amazon AWS, Cloudflare, and Google Cloud, maintain dedicated 24/7 abuse reporting channels because malicious traffic often originates from compromised servers, not the account holder.
Can you trace an IP address?
Yes, you can trace an IP address to get a general idea of its location. However, you won't be able to pinpoint someone's exact address. An IP trace may reveal the city or region where the IP is registered or where the ISP operates, but it won't show a home address or personal details.
In practice, even law enforcement typically requires subpoenas or warrants to obtain subscriber details from an ISP, which underscores how limited public IP tracing truly is.
How do I find my IP address?
You can find your public IP address on the What Is My IP homepage, where your IPv4, and IPv6 if available, will appear automatically. You can also find it on the IP lookup tool page.
Note that when you search IP addresses through the tool, the result you get is your public IP address. This is different from your private IP address, which you find through your computer. Read about how to check an IP address in Windows 7, Windows 10, Windows 11, or how to find an IP on an iPad to learn how to find your device's private IP address.
How to update or correct your IP location
If your IP location is incorrect, look up your IP and contact the third-party IP location data providers listed in your results to request a correction.
Allow time for the updates to propagate. Then, try using the lookup tool again to check your IP address location again to confirm that the information is now correct. You can also confirm updates listed on third-party providers’ websites.
Can you look up someone's IP address for free?
Yes, using the IP address tracker tool, you can search up addresses and receive the geolocation of an IP address for free. The information you'll receive often includes the country, state, and city of the located address.
Keep in mind that these details come from third-party geolocation databases, which aggregate ISP registration data rather than a user’s real-time physical location.
Why do I need to perform an IP address lookup?
IP address lookup is important for finding security threats, tracking spammers and hackers, and solving network problems. Businesses and individuals can also use it for marketing purposes. They can target specific regions or demographics with ads or information.
These lookups also help users verify whether VPNs, proxies, or privacy tools are working as expected, ensuring their public-facing IP matches their intended location.

No, it's not illegal to look up someone's IP address. However, using IP data to stalk, harass, or attempt unauthorized access to a system is illegal.
How does an IP address tracker work?
An IP address tracker uses third-party geolocation databases that map IP addresses to track the location of the inputted IP. When you enter an IP, the tool checks the database and returns available details such as the IP's general location, ISP, hosting provider, and network type. Results are estimates, since IP address ownership and routing can change over time.
How do I check my device IP address?
You can find your device's private IP address in your device's network settings, or if you want to check your public IP, you can do it on the WhatIsMyIP homepage.
