Which DNS server should I use?

We recommend our DNS servers since some content delivery networks incorrectly resolve lookup requests and cause requesting parties to be misdirected.

DNS resolver servers for IPv4 and IPv6 addresses for our customers are:

ns10.init7.net 77.109.128.2
ns10.init7.net 2001:1620:2777:1::10

ns20.init7.net 213.144.129.20
ns20.init7.net 2001:1620:2777:2::20

DNS resolvers are normally configured automatically. The use of our DNS resolvers is limited and only customers have access.

You can find more information about DNS on Wikipedia.
