About this tool
Enter an IP address or a domain name. For a domain we resolve its DNS records and use the first public address for the geolocation and whois sections. Lookups normally run on our own server; if local DNS is blocked, an external checker may be used.
What each value means
- Geolocation & provider:
- Location: approximate city, region and country the address is registered to.
- Provider: the organisation (ISP or hosting company) and its autonomous system number (ASN).
- Timezone: time zone associated with the detected location.
- Coordinates / Accuracy radius: approximate latitude and longitude, plus how far off the estimate may be.
- DNS records:
- A / AAAA: IPv4 and IPv6 addresses the name points to.
- MX: mail servers with their priority (lower is preferred).
- NS: authoritative name servers for the zone.
- TXT: free-form text records (SPF, verification tokens, etc.).
- Reverse DNS (PTR): for an IP address, the hostname registered for it.
- Whois registration: registrar, creation/expiry dates, status and nameservers as published by the registry, followed by the full raw response.
