nslookup
nslookup (from name server lookup) is a network administration command-line tool for querying the Domain Name System (DNS) to obtain the mapping between domain name and IP address, or other DNS records. Overview[edit]nslookup was a member of the BIND name server software. Early[when?] in the development of BIND 9, the Internet Systems Consortium planned to deprecate nslookup in favor of host and dig. This decision was reversed in 2004 with the release of BIND 9.3[1] and nslookup has been fully supported since then. Unlike dig, nslookup does not use the operating system's local Domain Name System resolver library to perform its queries, and thus may behave differently. Additionally, vendor-provided versions may include output of other sources of name information, such as host files, and Network Information Service. Some behaviors of nslookup may be modified by the contents of resolv.conf.[2] The Linux version of nslookup was written by Andrew Cherenson.[3] The ReactOS version was developed by Lucas Suggs and is licensed under the GPL.[4] Usage[edit]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 ( See also[edit]
