What is a public IP address?

Your public IP address is the unique identifier that your Internet Service Provider (ISP) assigns to your connection, allowing you to communicate with other devices across the Internet. It works like your device's "postal address" on the network.

Why should I know my IP?

Knowing your public IP allows you to:

• See how websites identify you when you browse.
• Check if your IP has changed (for example, after restarting your router).
• Diagnose network problems.
• Protect your privacy (for example, by using VPNs or proxies).

Is my IP static or dynamic?

Most home connections use a dynamic IP, which can change periodically. If you need your IP address to remain the same (for example, to access your home network remotely), you will need a static IP.

How can I change my IP?

Some common ways to change your IP include:

• Restarting your router.
• Using a VPN service.
• Requesting a new IP or a static IP from your ISP.
