Reading the data
Addresses and endpoint names come from each provider's documentation, reviewed . Resolver profiles have different filtering policies; select the profile that matches your network's requirements.
The IP reports combine these address-specific facts with IPQuery's network lookup. A geolocation estimate is not a DNS server location guarantee. We do not measure resolver uptime, response time or the path from your network.
