Domain Name System query(DNS query)
A request that a DNS client (usually a resolver) submits to a name server to obtain information from the Domain Name System.
A DNS query often contains a request for the Internet Protocol (IP) address of a specific host or domain name. For this type of query, the name server responds with either 1) the requested IP address, 2) the IP address of the next name server in the path of authority, or 3) an NXDOMAIN error code, which signals that the requested host or domain name does not exist.
