Public recursive name server

A public recursive name server is a name server that networked computers may use for Internet directory services in place of or in addition to name servers belonging to the Internet service providers to which the devices are connected. Reasons for using these services include:

Public DNS resolver operators often cite increased privacy as an advantage of their services; critics of public DNS services have cited the possibility of mass data collection targeted at the public resolvers as a potential risk of using these services. Several services now support secure DNS lookup transport services such as DNS over TLS and DNS over HTTPS.
