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.
