r-gdns
To address the problem of insecurity of 'UDP'-based 'DNS' requests, 'Google Public DNS' offers 'DNS' resolution over an encrypted 'HTTPS' connection. 'DNS-over-HTTPS' greatly enhances privacy and security between a client and a recursive resolver, and complements 'DNSSEC' to provide end-to-end authenticated 'DNS' lookups. Functions that enable querying individual requests that bulk requests that return detailed responses and bulk requests are both provided. Support for reverse lookups is also provided. See <https://developers.google.com/speed/public-dns/docs/dns-over-https> for more information.
