An IP address is a unique identifier for devices on the internet, used to recognize your network location and connection source. Every time you visit a website, the server records your IP information.

Without using a proxy or VPN, most websites can see your real IP address and use it to determine your geographic location and network environment.

Although an IP cannot directly pinpoint personal identity, long-term exposure of a real IP may lead to account risk controls, ad tracking, regional restrictions, or bans.

Possible reasons include: the IP is shared by many users, previous violations, the IP belongs to a data center, frequent account switching, or accessing sensitive platforms.

If you are using a dynamic IP, mobile network, or proxy service, it is normal for the IP address to change.
