What Is an IP Address
An IP address is your device's unique identifier on the internet. It is like a mailing address for your connection. Websites use it to send data back to you. Your IP reveals your approximate location and ISP. IPv4 addresses are running out. IPv6 is the replacement with many more addresses.
Public vs Private IP
Your router assigns private IPs to devices on your local network (like 192.168.x.x). Your public IP is assigned by your ISP and identifies your entire household on the internet. All devices share one public IP unless you have a special setup.
Why Your IP Matters
Websites use your IP for geolocation. Streaming services check your IP for regional content. Some services block certain IP ranges. Your IP changes if you restart your router or contact your ISP. Use a VPN to hide your IP. Run our DNS speed test to check your DNS performance too.
