e9a9ae4fc627f24cb960a3008f2723ba9a55b274Brian Wellington is a program to query Internet domain name servers. <command>Nslookup</command>

e9a9ae4fc627f24cb960a3008f2723ba9a55b274Brian Wellington has two modes: interactive and non-interactive. Interactive mode allows

d1bdeae7bb7a0642170d5476c2fd901db3028143Andreas Gustafsson the user to query name servers for information about various hosts and

d1bdeae7bb7a0642170d5476c2fd901db3028143Andreas Gustafsson domains or to print a list of hosts in a domain. Non-interactive mode

d1bdeae7bb7a0642170d5476c2fd901db3028143Andreas Gustafsson is

d111a46c88adda33a93839f4934e127b6147d87dBob Halley used to print just the name and requested information for a host or

d111a46c88adda33a93839f4934e127b6147d87dBob Halley domain.
