nslookup operates in interactive or non-interactive mode. When used interactively by invoking it without arguments or when the first argument is - (minus sign) and the second argument is a hostname or Internet address of a name server, the user issues parameter configurations or requests when presented with the nslookup prompt (>).
Multicast DNS (mDNS) is a computer networking protocol that resolves hostnames to IP addresses within small networks that do not include a local name server.It is a zero-configuration service, using essentially the same programming interfaces, packet formats and operating semantics as unicast Domain Name System (DNS).
This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header.It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header.
They are network protocol agnostic, and support both IPv4 and IPv6. It is the recommended interface for name resolution in building protocol independent applications and for transitioning legacy IPv4 code to the IPv6 Internet. Internally, the functions may use a variety of resolution methods not limited to the Domain Name System (DNS).

DNS over HTTPS (DoH) is a protocol for performing remote Domain Name System (DNS) resolution via the HTTPS protocol. A goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data by man-in-the-middle attacks [1] by using the HTTPS protocol to encrypt the data between the DoH client and the DoH-based DNS resolver.

Google Public DNS is a Domain Name System (DNS) service offered to Internet users worldwide by Google.It functions as a recursive name server.Google Public DNS was announced on December 3, 2009, [1] in an effort described as "making the web faster and more secure."
dig is a network administration command-line tool for querying the Domain Name System (DNS).. dig is useful for network troubleshooting and for educational purposes. [2] It can operate based on command line option and flag arguments, or in batch mode by reading requests from an operating system file.
