Upstream DNS Providers
The Pi-hole setup offers 8 options for an upstream DNS Provider during the initial setup.

During the pi-hole installation you select 1 of the 7 preset providers or enter one of your own. Below you can find more information on each of the DNS Providers, along with some additional providers which have different kinds of extra filtering options (spam, phishing, adult content, etc).

OpenDNS Home (owned by Cisco)¶
Built-in features include a phishing filter, this is the OpenDNS version the Pi-hole would use if you select it during setup.
OpenDNS also provides the *OpenDNS FamilyShield (free)- option. The service blocks pornographic content, including our “Pornography,” “Tasteless,” and “Sexuality” categories, in addition to proxies and anonymizers (which can render filtering useless). It also blocks phishing and some malware.
