About location and DNSSEC status

The location of the servers has been stated by using GeoIP Tool and the IPFire Location Block server. However, it might be possible that the location is wrong (or has been changed meanwhile).

The servers that are marked with "Anycast" are using anycasts so that traffic will be routed to the nearest of the many instances that are there on the network. Thereof the exact location of the server(s) cannot be determined. Worse, different configurations of Anycast instances cannot be determined reliable.

Security Considerations

A DNS server has a very powerful function in network topology. Please keep in mind that it might log your queries (which is a huge information leak).

Further, not all of the DNS servers listed above return correct answers in any case. Some of them return failures for harmful or malicious sites. Check the operators website for more information on this topic.

For security reasons, it is required to use DNS servers which support DNSSEC. For privacy and availability reasons, avoid using just one providers' DNS servers.
