-.SH NAME
-nslookup \- query Internet name servers interactively
-.SH SYNOPSIS
-.B nslookup
-[
-.I \-option ...
-]
-[
-.I host-to-find
-| \- [
-.I server
-]]
-.SH DESCRIPTION
-.I 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.
-.sp 1
-.SH ARGUMENTS
-Interactive mode is entered in the following cases:
-.IP a) 4
-when no arguments are given (the default name server will be used),
-.IP b) 4
-when the first argument is a hyphen (\-) and the second argument
-is the host name or Internet address of a name server.
-.LP
-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.
-.LP
-The options listed under the ``set'' command below can be specified in
-the .nslookuprc file in the user's home directory if they are listed
-one per line. 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:
-.sp .5v
- nslookup \-query=hinfo \-timeout=10
-.sp .5v
-.SH "INTERACTIVE COMMANDS"
-Commands may be interrupted at any time by typing a control-C.
-To exit, type a control-D (EOF) or type exit.
-The command line length must be less than 256 characters.
-To treat a built-in command as a host name,
-precede it with an escape character (\e).
-\fBN.B.\fP an unrecognized command will be interpreted as a host name.
-.sp .5v
-.IP "\fIhost\fP [\fIserver\fP]"
-Look up information for \fIhost\fP using the current default server
-or using \fIserver\fP if specified.
-If \fIhost\fP is an Internet address and the query type is A or PTR, the
-name of the host is returned.
-If \fIhost\fP is a name and does not have a trailing period, the default
-domain name is appended to the name. (This behavior depends on the state of the
-\fBset\fP options \fBdomain\fP, \fBsrchlist\fP,
-\fBdefname\fP, and \fBsearch\fP).
-To look up a host not in the current domain, append a period to
-the name.
-.sp 1
-.IP "\fBserver\fP \fIdomain\fP"
-.ns
-.IP "\fBlserver\fP \fIdomain\fP"
-Change the default server to \fIdomain\fP.
-\fBLserver\fP uses the initial server to look up
-information about \fIdomain\fP while \fBserver\fP
-uses the current default server.
-If an authoritative answer can't be found, the names of servers
-that might have the answer are returned.
-.sp 1
-.IP \fBroot\fP
-Changes the default server to the server for the root of the domain name space.
-Currently, the host ns.internic.net is used.
-(This command is a synonym for \fBlserver ns.internic.net.\fP)

-.sp 1
-.IP "\fBfinger\fP [\fIname\fP] [\fB>\fP \fIfilename\fP]"
-.ns
-.IP "\fBfinger\fP [\fIname\fP] [\fB>>\fP \fIfilename\fP]"
-Connects with the finger server on the current host.
-The current host is defined when a previous lookup for a host
-was successful and returned address information (see the
-\fBset querytype=A\fP command).
-\fIName\fP is optional.
-\fB>\fP and \fB>>\fP can be used to redirect output in the
-usual manner.
-.sp 1

-.ns
-.IP "\fBls\fR [\fIoption\fR] \fIdomain\fR [\fB>>\fR \fIfilename\fR]"
-List the information available for \fIdomain\fP, optionally creating
-or appending to \fIfilename\fP.
-The default output contains host names and their Internet addresses.
-.I Option
-can be one of the following:
-.RS
-.IP "\fB\-t \fIquerytype\fP" 4
-lists all records of the specified type (see \fIquerytype\fP below).
-.IP \fB\-a\fP 4
-lists aliases of hosts in the domain.
-synonym for \fB\-t\ \ CNAME\fP.
-.IP \fB\-d\fP 4

-Change the default domain name to \fIname\fP.
-The default domain name is appended to a lookup request depending on the
-state of the \fBdefname\fP and \fBsearch\fP options.
-The domain search list contains the parents of the default domain if it has
-at least two components in its name.
-For example, if the default domain
-is CC.Berkeley.EDU, the search list is CC.Berkeley.EDU and Berkeley.EDU.
-Use the \fBset srchlist\fP command to specify a different list.
-Use the \fBset all\fP command to display the list.

-Change the default domain name to \fIname1\fP and the domain search list
-to \fIname1\fP, \fIname2\fP, etc. A maximum of 6 names separated by slashes (/)

-For example,
-.sp .5v
- set\ srchlist=lcs.MIT.EDU/ai.MIT.EDU/MIT.EDU
-.sp .5v
-sets the domain to lcs.MIT.EDU and the search list to the three names.
-This command overrides the

-Use the \fBset all\fP command to display the list.
-.br
-(Default = value based on hostname, /etc/resolv.conf or LOCALDOMAIN,

-.br
-(Default = defname, abbreviation = [no]def)
-.IP "\fB[no]search\fP"
-If the lookup request contains at least one period but doesn't end

-time (changed with \fBset timeout=\fIvalue\fR)
-and a certain number of retries (changed with \fBset retry=\fIvalue\fR).
-.IP "No response from server" 5
-No name server is running on the server machine.
-.IP "No records" 5
-The server does not have resource records of the current query type for the
-host, although the host name is valid.
-The query type is specified with the \fBset querytype\fP command.
-.IP "Non-existent domain" 5
-The host or domain name does not exist.
-.IP "Connection refused" 5
-.ns
-.IP "Network is unreachable" 5
-The connection to the name or finger server could not be made
-at the current time.
-This error commonly occurs with \fBls\fP and \fBfinger\fP requests.
-.IP "Server failure" 5
-The name server found an internal inconsistency in its database
-and could not return a valid answer.
-.IP "Refused" 5
-The name server refused to service the request.
-.IP "Format error" 5
