NSLOOKUP(1) BIND9 NSLOOKUP(1)

NAME
nslookup - query Internet name servers interactively

SYNOPSIS
nslookup [-option] [name | -] [server]

DESCRIPTION
Nslookup is a program to query Internet domain name servers. Nslookup
has two modes: interactive and non-interactive. Interactive mode allows
the user to query name servers for information about various hosts and
domains or to print a list of hosts in a domain. Non-interactive mode
is used to print just the name and requested information for a host or
domain.

ARGUMENTS
Interactive mode is entered in the following cases:

1. when no arguments are given (the default name server will be used)

    2. when the first argument is a hyphen (-) and the second argument is
       the host name or Internet address of a name server.

   Non-interactive mode is used when the name or Internet address of the
   host to be looked up is given as the first argument. The optional
   second argument specifies the host name or address of a name server.

   Options can also be specified on the command line if they precede the
   arguments and are prefixed with a hyphen. For example, to change the
   default query type to host information, and the initial timeout to 10
   seconds, type:

       nslookup -query=hinfo  -timeout=10

   The -version option causes nslookup to print the version number and
   immediately exits.

INTERACTIVE COMMANDS
host [server]
Look up information for host using the current default server or
using server, if specified. If host is an Internet address and the
query type is A or PTR, the name of the host is returned. If host
is a name and does not have a trailing period, the search list is
used to qualify the name.

To look up a host not in the current domain, append a period to the
       name.

   server domain

   lserver domain
       Change the default server to domain; lserver uses the initial
       server to look up information about domain, while server uses the
       current default server. If an authoritative answer can't be found,
       the names of servers that might have the answer are returned.

   set keyword[=value]
       This command is used to change state information that affects the
       lookups. Valid keywords are:

       all
           Prints the current values of the frequently used options to
           set. Information about the current default server and host is
           also printed.

       class=value
           Change the query class to one of:

           IN
               the Internet class

           CH
               the Chaos class

           HS
               the Hesiod class

           ANY
               wildcard

           The class specifies the protocol group of the information.

           (Default = IN; abbreviation = cl)

        [no]debug
           Turn on or off the display of the full response packet and any
           intermediate response packets when searching.

           (Default = nodebug; abbreviation = [no]deb)

        [no]d2
           Turn debugging mode on or off. This displays more about what
           nslookup is doing.

           (Default = nod2)

       domain=name
           Sets the search list to name.

        [no]search
           If the lookup request contains at least one period but doesn't
           end with a trailing period, append the domain names in the
           domain search list to the request until an answer is received.

           (Default = search)

       port=value
           Change the default TCP/UDP name server port to value.

           (Default = 53; abbreviation = po)

       querytype=value

       type=value
           Change the type of the information query.

           (Default = A; abbreviations = q, ty)

        [no]recurse
           Tell the name server to query other servers if it does not have
           the information.

           (Default = recurse; abbreviation = [no]rec)

       ndots=number
           Set the number of dots (label separators) in a domain that will
           disable searching. Absolute names always stop searching.

       retry=number
           Set the number of retries to number.

       timeout=number
           Change the initial timeout interval for waiting for a reply to
           number seconds.

        [no]vc
           Always use a virtual circuit when sending requests to the
           server.

           (Default = novc)

        [no]fail
           Try the next nameserver if a nameserver responds with SERVFAIL
           or a referral (nofail) or terminate query (fail) on such a
           response.

           (Default = nofail)

RETURN VALUES
nslookup returns with an exit status of 1 if any query failed, and 0
otherwise.

macOS NOTICE
The nslookup command does not use the host name and address resolution
or the DNS query routing mechanisms used by other processes running on
macOS. The results of name or address queries printed by nslookup may
differ from those found by other processes that use the macOS native
name and address resolution mechanisms. The results of DNS queries may
also differ from queries that use the macOS DNS routing library.

FILES
