If you’ve ever searched “What is my IP?”, you’re probably trying to troubleshoot an internet issue, improve your online security, or configure a device, right?
An IP (Internet Protocol) address is a unique identifier assigned to every device connected to the internet or a local network. Think of it as a home address but for your internet connection.
Without an IP address, websites wouldn’t know where to send the information you request. Whether you’re visiting a website, streaming a video, or sending an email, your IP address plays a vital role in making that connection possible.
There are two main versions of IP addresses:
IPv4 – The most common format, such as 192.168.1.1
IPv6 – A newer format designed to support the growing number of internet-connected devices.
Your public IP address is assigned by your internet service provider (ISP) and is visible to websites and online services you visit. It may change periodically unless you have purchased a static IP address.
Your device also has a private IP address, which is used within your home or office network and isn’t visible to the wider internet.
If you’ve already searched this, then you’ll see that Google usually displays your public IP address at the top of search results, but you can find more information in your device’s network settings.
Your IP address affects more than simply connecting to websites.
It can influence:
Businesses also use IP addresses for firewall rules, remote working, website analytics and fraud prevention.
Many people confuse these two types of IP addresses. The main differences between the tw include:
Public
Assigned by your internet provider and visible on the internet. Other websites can also see your address.
Private
Assigned by your router and only used in your local network. Your address is hidden from external websites.
An IP address can reveal an approximate location, such as your town, city or region, but it cannot reveal your exact home address.
If you’re concerned about privacy, a VPN (Virtual Private Network) masks your public IP address by routing your internet traffic through another server.
In many cases, restarting your router may result in a new dynamic IP address. Alternatively, using a VPN changes the IP address that websites see.
Websites need your IP address to know where to send the information you’ve requested. Without it, internet communication wouldn’t work.
