Frequently Asked Questions

Your IP address is the unique number assigned to your device when it connects to the internet. It's like your device's "digital address". You can see your public IP address, location, and other details on this page.
An IP address (Internet Protocol address) is a numeric label every device gets when online. It functions like a mailing address for your device, allowing data to know where to go. For example, 192.168.1.1 is an IP address. IP addresses let computers, smartphones, and other devices send and receive information on the internet.
A public IP address is the outward-facing address provided by your Internet Service Provider – it's how websites and services see your device on the internet. In contrast, a private IP address is used inside your home/office network (assigned by your router to your phone, laptop, etc.). Private IPs (often starting with 192.168 or 10.x.x.x) are not reachable directly from the internet; public IPs are how your network as a whole is identified online.
Your public IP is easy to find – you're looking at it right now at the top of this page. If you need your private IP (local network IP) on a device, here's how: On Windows, you can run the ipconfig command in Command Prompt or check your network adapter details. On Mac, go to System Preferences > Network and look for the IP next to your connected interface. On mobile devices, check the Wi-Fi settings for the network you're on – it will show an IP address. These steps will show the private IP your router has given your device.
IP geolocation is the process of mapping an IP address to its approximate location, including country, city, region, timezone, ISP, and ASN using GeoIP data. It is widely used for fraud detection, cybersecurity, content localization, geotargeting, analytics, and location-based personalization.
Simply knowing your IP address is usually not enough to hack you. An IP by itself only reveals your general location and ISP, not any passwords or direct access. However, attackers could target your IP with things like DDoS attacks (overwhelming your connection) or try to exploit open ports if your system is vulnerable. It's important to have a good firewall and keep your system updated. Generally, as long as you haven't exposed unsafe services to the internet and you use a router (which acts as a firewall), your risk of being "hacked" just via IP is very low.
IPv4 and IPv6 are two versions of IP addresses. IPv4 is the older format (e.g., 203.0.113.45) and uses 32- bit numbers, allowing about 4.3 billion addresses total. IPv6 is the newer format (e.g., 2001:0db8::68) and uses 128-bit numbers, providing trillions upon trillions of addresses. IPv6 was introduced to ensure we don't run out of IP addresses and also includes improvements in efficiency and security. Many devices now support both IPv4 and IPv6.
Your IP address can reveal general information such as the city/region and country you're in, and the name of your Internet Service Provider (ISP). For example, it might show "New York, USA – Verizon Fios". However, it does not expose your exact home address or personal identity on its own. Websites use IP data for location-based services or to tailor content, but they can't get your name or precise location just from the IP.
It's normal for your public IP address to change periodically. Most ISPs use dynamic IP addressing, meaning you get a temporary IP that can change when you restart your router or after a certain time period. For instance, your IP might reset to a new number overnight or when the network reassigns it. If you switch networks (move from home Wi-Fi to a coffee shop Wi-Fi or to mobile data), you'll also get a different IP. The only way to have a constant IP is if you pay for a static IP, which remains the same.
In most cases, you don't need to change your IP address. It doesn't improve normal browsing speed or anything like that. However, there are a few situations where changing your IP might help: for privacy (to prevent websites from knowing your location), to bypass an IP-based ban or geoblock, or to troubleshoot network issues. If you're experiencing problems (like being unable to access certain sites) or you want a fresh identity online, you might consider it. Otherwise, for typical users, it's fine to keep the IP your ISP assigns you.
The most common way to mask or change your public IP is to use a VPN (Virtual Private Network). A VPN will route your internet traffic through another server and give you a different IP address (often you can choose a location, like getting a UK IP while you're in the US). This hides your real IP from websites. Other options include using a proxy server or the Tor browser (which bounces your connection through multiple nodes). Even simply tethering to your phone or restarting your router can sometimes change your IP (if your ISP assigns a new one). But for a reliable change and privacy, VPNs are the go-to solution.
