   en.wikipedia.org/wiki/Google_Public_DNS

   Google Public DNS was announced on December 3, 2009, [1] in an effort described as "making the web faster and more secure." [2] [3] As of 2018, it is the largest public DNS service in the world, handling over a trillion queries per day. [4] Google Public DNS is not related to Google Cloud DNS, which is a DNS hosting service.

3. Public recursive name server - Wikipedia

   en.wikipedia.org/wiki/Public_recursive_name_server

   A public recursive name server (also called public DNS resolver) is a name server service that networked computers may use to query the Domain Name System (DNS), the decentralized Internet naming system, in place of (or in addition to) name servers operated by the local Internet service provider (ISP) to which the devices are connected.

4. List of DNS record types - Wikipedia

   en.wikipedia.org/wiki/List_of_DNS_record_types

   This list of DNS record types is an overview of resource records (RRs) permissible in zone files of the Domain Name System (DNS). It also contains pseudo-RRs. It also contains pseudo-RRs. Resource records

5. Reverse DNS lookup - Wikipedia

   en.wikipedia.org/wiki/Reverse_DNS_lookup

   The modern "reverse DNS lookup" should not be confused with the now-obsolete "inverse query" (IQUERY) mechanism specified in RFC 1035: Inverse queries take the form of a single resource record (RR) in the answer section of the message, with an empty question section. The owner name of the query RR and its time to live (TTL

6. dig (command) - Wikipedia

If ANY queries do not enumerate multiple records, the only option is to request each record type (e.g. A, CNAME, or MX) individually.

7. CNAME record - Wikipedia

   en.wikipedia.org/wiki/CNAME_record

   However, if the resolver is specifically told to look for CNAME records, the canonical name (right-hand side) is returned, rather than restarting the query. The canonical name that a CNAME record points to can be anywhere in the DNS, whether local or on a remote server in a different DNS zone. For example, consider a DNS zone as follows:

8. DNS over TLS - Wikipedia

   en.wikipedia.org/wiki/DNS_over_TLS

   DNS over TLS (DoT) is a network security protocol for encrypting and wrapping Domain Name System (DNS) queries and answers via the Transport Layer Security (TLS) protocol. The goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data via man-in-the-middle attacks .

9. NAPTR record - Wikipedia

   en.wikipedia.org/wiki/NAPTR_record

   A Name Authority Pointer (NAPTR) is a type of resource record in the Domain Name System of the Internet. [1] [2]NAPTR records are most commonly used for applications in Internet telephony, for example, in the mapping of servers and user addresses in the Session Initiation Protocol (SIP).
