Frequently asked questions (FAQs) about this topic

How do I check my public IP address?

A public IP lookup tool shows the address your internet connection presents to websites and services. It is different from your local router address, which only works inside your home or office network. Good tools display both IPv4 and IPv6 when available.

What is the difference between public and private IP addresses?

Public IP addresses are reachable on the internet and are usually assigned by your ISP. Private IP addresses are used inside local networks, such as home Wi-Fi or office LANs, and are not directly reachable from outside. If a device has trouble connecting, checking both can help narrow down the issue.

Can IP address tools show the location of a device?

Many lookup tools estimate the country, region or city linked to an IP address, but the result is not exact. Mobile networks, VPNs and corporate gateways can make the location appear different from the device's real position. Treat geolocation as a clue, not proof.

Why does my IP address keep changing?

Most internet providers use dynamic IP addresses, which can change after a router restart or at regular intervals. This is normal for many home connections. A static IP is more stable, but it is usually a paid or business-grade option.
