European alternatives to OpenDNS

OpenDNS is a public DNS resolver, now part of Cisco. Rather than using the resolver your internet provider hands you, you point a device or a router at its addresses and it answers the lookups that turn domain names into IP addresses. It is often chosen for its filtering options, which can block whole categories of sites across a network.

DNS queries add up to a complete list of every service you contact, which makes the resolver an unusually revealing piece of infrastructure. Schools, companies and households that care where that log lives can change it in minutes, since this is a setting rather than a migration. A European alternative to OpenDNS is a straight swap. DNS4EU is a European resolver initiative, quad9 is a widely used non profit resolver, and UncensoredDNS and Mullvad DNS are smaller operators.
