IP Address Basics
What is an IP address?
An IP (Internet Protocol) address is a unique numerical identifier assigned to devices connected to a network. It serves as a digital address that allows devices to communicate with each other over the internet. Think of it like a postal address for your computer or smartphone.
What is the difference between IPv4 and IPv6?
IPv4 addresses are 32-bit numbers (like 192.168.1.1) and can support about 4.3 billion unique addresses. IPv6 addresses are 128-bit numbers (like 2001:0db8:85a3:0000:0000:8a2e:0370:7334) and can support trillions of unique addresses, solving the IPv4 address exhaustion problem.
How do I find my IP address?
You can find your public IP address by visiting our ScanIPInfo tool, which will automatically detect and display your current IP address along with detailed information about your location and network.
Privacy & Security
Can someone track me using my IP address?
Your IP address can reveal your approximate location (city/region level) and ISP information, but it cannot pinpoint your exact address. However, it's always good practice to use VPNs or other privacy tools if you're concerned about online privacy.
What is a VPN and how does it affect my IP?
A VPN (Virtual Private Network) creates a secure, encrypted connection between your device and a remote server. When you use a VPN, your IP address appears to be from the VPN server's location, masking your true location and providing additional privacy.
How can I protect my IP address?
You can protect your IP address by using a VPN, Tor browser, or proxy servers. Additionally, avoid clicking on suspicious links, keep your software updated, and use strong passwords to prevent unauthorized access to your network.
Network Diagnostics
What is geolocation and how accurate is it?
Geolocation is the process of determining the geographical location of an IP address. It's typically accurate to the city or region level, but not to the exact street address. Accuracy depends on various factors including ISP data and network infrastructure.
Why does my IP address change?
Your IP address can change due to several reasons: your ISP assigns dynamic IPs that change periodically, you reconnect to your network, you switch between different networks (WiFi vs mobile data), or you use a VPN service.
What is an ISP and why is it important?
An ISP (Internet Service Provider) is the company that provides you with internet access. Your ISP information is important because it determines your internet speed, reliability, and can affect your online experience and privacy.
Technical Questions
What is device fingerprinting?
Device fingerprinting is a technique that collects information about your device's characteristics (browser type, screen resolution, installed fonts, etc.) to create a unique identifier. This can be used for tracking purposes, even when cookies are disabled.
How does speed testing work?
Speed testing measures the time it takes for data to travel between your device and a server. It tests latency (ping time), download speed, and upload speed to give you a comprehensive view of your internet connection performance.
What is the difference between public and private IP addresses?
A public IP address is assigned by your ISP and is visible to the internet. A private IP address (like 192.168.x.x or 10.x.x.x) is used within your local network and is not directly accessible from the internet.
