Frequently asked questions
Is IP geolocation exact?
No. IP location data is approximate and provider-dependent, so use it as context rather than precise physical location.
Can I enter a domain name?
Yes. NerdTools resolves public hostnames first, then looks up IP information for the resolved address.
