OpenDNS

OpenDNS is the consumer brand of Cisco Umbrella and has two public addresses that need no account. Standard (208.67.222.222 and 208.67.220.220) blocks malware and phishing domains and does no content filtering. FamilyShield (208.67.222.123 and 208.67.220.123) adds a fixed filter for adult content, proxies and anonymisers, meant to be set on the home router and forgotten. To pick categories, add allow-lists or see statistics you need a free OpenDNS Home account and to keep your public IP updated.

Cisco keeps query logs for security purposes and operates from the United States, so it is not the pick for anyone after zero logging: Quad9 or Cloudflare fit that better. In exchange it is a veteran service (since 2006, and the creator of DNSCrypt), stable, with DoH and DoT. In our measurement from Madrid it answered in 18 ms cached and 33 ms cold with no loss: fine, though slower than Cloudflare or Quad9.

Not the right choice if you want ad blocking (it doesn't; see AdGuard), if you need customisation without an account (Control D or NextDNS allow it) or if privacy is the priority. A good choice for a family router that needs an adult filter nobody has to maintain, or a small office that wants the OpenDNS Home dashboard.
