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 (>).
The Link-Local Multicast Name Resolution (LLMNR) is a protocol based on the Domain Name System (DNS) packet format that allows both IPv4 and IPv6 hosts to perform name resolution for hosts on the same local link.
The function getnameinfo() converts the internal binary representation of an IP address in the form of a pointer to a struct sockaddr into text strings consisting of the hostname or, if the address cannot be resolved into a name, a textual IP address representation, as well as the service port name or number. The function prototype is specified ...
SSM destination addresses must be in the ranges 232.0.0.0/8 for IPv4. For IPv6 current allowed SSM destination addresses are specified by ff3x::/96, where the hexadecimal digit x represents the scope. [1] Note however that the allocation may be extended in the future so receivers and network equipment should treat any ff3x::/32 address as SSM. [2]
IPv4 address 224.0.0.251 or IPv6 address ff02::fb; UDP port 5353; When using Ethernet frames, the standard IP multicast MAC address 01:00:5E:00:00:FB (for IPv4) or 33:33:00:00:00:FB (for IPv6) The payload structure is based on the unicast DNS packet format, consisting of two parts—the header and the data. [5]
Reverse DNS lookups for IPv4 addresses use the special domain in-addr.arpa.In this domain, an IPv4 address is represented as a concatenated sequence of four decimal numbers, separated by dots, to which is appended the second level domain suffix .in-addr.arpa.

They are PTR queries for subdomains of in-addr.arpa (for IPv4 addresses) [3] and ip6.arpa (for IPv6 addresses). [4] For example, to find the domain name associated with the IP address 203.0.113.22, one would send a PTR query for 22.133.0.203.in-addr.arpa. Misconfigured hosts [5] often send reverse DNS queries for private addresses to the public ...
