FAQ

Questions about IP & Network Information Checker

Questions that make decisions easier before use are summarized first.

Can it also show my global IP?

Yes. It is fetched only when needed, as that part requires an external request.

Is the information stored?

No. It is designed for checking and copying, not for permanent storage.

Can it show IPv6?

The address shown depends on your connection. IPv4 or IPv6 is displayed based on your network. Showing both simultaneously is not currently supported.

Is the information updated in real time?

Global IP is fetched manually. Other information is retrieved when the page loads and is not refreshed automatically.

Can I use it on a smartphone?

Yes. Device and connection information can be checked from a smartphone as well.

Can I copy and share the information I see?

Yes. Each piece of information can be copied to the clipboard with one click.
