nslookup - query Internet name servers interactively 查询Internet名称服务器。SYNOPSIS

nslookup [-option] [name | -] [server]DESCRIPTION 描述

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.Nslookup是一个用来查询互联网域名服务器的程序，网路资讯查询有两种模式，交互式的与非交互式的，交互模式允许用户查询有关各种主机和域的信息或打印列表域内的主机，非交互模式用于仅打印主机或域的名称和请求信息。ARGUMENTS 参数

Interactive mode is entered in the following cases: 在以下情况下输入交互模式: 1. when no arguments are given (the default name server will be used) 当没有给出参数时(默认的名称服务器将被使用 2. when the first argument is a hyphen (-) and the second argument is the host name or Internet address of a name server. 当第一个参数是连字符(-)时，第二个参数是名称服务器的主机名或Internet地址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. 当查找的主机的名称或Internet地址作为第一个参数时，使用非交互模式。可选的第二个参数指定名称服务器的主机名或地址。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: 还可以在命令行中指定选项，如果选项在参数之前，并以连字符作为前缀，例如：若要将默认查询类型更改为主机信息，初始超时更改为10秒，请输入:

nslookup -query=hinfo -timeout=10INTERACTIVE COMMANDS 交互式命令

host [server] 主机名

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. 如果指定，请使用当前默认服务器或使用服务器查找主机信息。 如果主机是一个Internet地址，而查询类型是A或PTR，则返回主机的名称。

如果主机是一个名称，并且没有末尾的句号，则使用搜索列表来限定名称。 To look up a host not in the current domain, append a period to the name. 要查找不在当前域中的主机，请在名称后面附加一个句点。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. 将默认服务器更改为domain;lserver使用初始服务器查找域信息，而服务器使用当前默认服务器。如果无法找到权威的答案，则返回可能有答案的服务器的名称。
