Public recursive name server
 | This article relies largely or entirely on a single source. (October 2016) |
A public recursive name server is a name server that devices 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 an alternative include:
- speed [1]
- filtering (security, ad-bloking, porn-blocking, etc) [2]
- reporting [3]
- avoiding censorship [4]
- redundancy (smart caching) [5]
