Every curious about how nslookup works? Then here is a bit of information that I came across recently:

Nslookup uses the domain devolution method. This means that if you search for host name: “test”, nslookup will append the domain suffix of the seaching computer to the host name (e.g. west.dns.windowswideopen.com). If the name is not found then nslookup will search the domain suffix devolved by one level :

test. west.dns.windowswideopen.com

test.dns.windowswideopen.com

test.windowswideopen.com

If test. west.dns.windowswideopen.com is queried then no devolution is performed.

There are two modes to nslookup: interactive and non-interactive.

Non-Interactive mode - user specifies all options in a single command e.g. nslookup <servername> dns-server - which specifies the DNS server to be used for the query.

nslookup will exit after the query is completed.

Interactive mode - Type nslookup only at the command line

? <enter> shows all commands

server <name> <enter> specifies the dns server to be used for query.DNSDNS
