FAQ
What is an IP address?
An IP address (Internet Protocol address) is a unique identifier assigned to devices on a network. It allows devices to communicate with each other over the internet or local networks, much like how a postal address helps to deliver mail to a specific location.
What's the difference between IPv4 and IPv6?
IPv4 is the older version of IP addresses, using a 32-bit format, allowing for around 4 billion unique addresses. IPv6 is the newer version, using a 128-bit format, offering many more possible IP addresses.
What is a VPN?
A VPN (Virtual Private Network) is a service that creates a secure, encrypted connection between your device and the internet. It masks your real IP address, providing privacy and allowing you to access content as if you were in a different location.
What is a proxy?
A proxy is an intermediary server between your device and the internet. It forwards requests from your device to websites, often masking your real IP address and providing anonymity, but not necessarily encrypting your data.
What is DNS?
DNS (Domain Name System) is like a phonebook for the internet. It translates domain names (like `example.com`) into IP addresses, allowing browsers to load websites by matching the domain to its associated IP address.
What is a port?
A port is a virtual entry point through which data travels to and from your device over a network. Different services and applications use different ports, allowing multiple processes to communicate over the same network connection.
Why is my IP address important?
Your IP address identifies your device on the internet and is used by websites and services to deliver content to you, track your location, or prevent fraud. It can also be used for geolocation purposes or to restrict access based on your region.
Is sharing my IP dangerous?
Sharing your IP address can expose you to privacy risks, such as targeted attacks or unwanted tracking. It can also potentially reveal your physical location. Using a VPN or proxy can help protect your privacy.
Can my ISP track my IP address?
Yes, your Internet Service Provider (ISP) assigns your IP address and can log your internet activity. Using a VPN or other privacy tools can help protect your browsing history from being seen by your ISP.
Is my IP address safe?
In general, an IP address by itself isn't dangerous, but it can be used to track your location and identify you online. While most websites use it for basic functions like delivering content, revealing your IP can make you more vulnerable to targeted attacks if malicious actors have access to it.
Does this information really matter since websites already have my IP?
While websites do collect your IP to serve you content, it's about the amount of detail that's accessible to others. Your IP address, combined with additional information like geolocation and ISP data, can be used to build a profile about you.
Is my IP permanent?
Most consumer-grade IPs will typically be reassigned occasionally, or when the router is unplugged and plugged back in.
