[英]Powershell : Get remote computer name
这不是 PowerShell 特定的问题或限制。 这是一个非常常见的网络管理员要做的事情。
正如 BACON 所指出的,您可以使用 nslookup,但 Windows 也提供了 .Net 命名空间,而 PowerShell 为这个用例提供了 DNS cmdlet。
在 Stackoverflow 上也被多次询问和回答。 在 MS 文档站点、TechNet、MSDN 和其他博客上有很好的文档记录。 例如
# Find machine name from IP address:
$ipAddress= "192.168.1.54"
[System.Net.Dns]::GetHostByAddress($ipAddress).Hostname
Resolve Hostname to IP Address:
$machineName= "DC1"
$hostEntry= [System.Net.Dns]::GetHostByName($machineName)
$hostEntry.AddressList[0].IPAddressToString
<#
Resolve Hostname for set of IP addresses from text file:
Use the below powershell script to find machine name for multiple IP addresses.
First create the text file ip-addresses.txt which includes one IP address in
each line. You will get the machinename list in the txt file machinenames.txt.
#>
Get-Content C:\ip-addresses.txt |
ForEach-Object{
$hostname = ([System.Net.Dns]::GetHostByAddress($_)).Hostname
if($? -eq $True) {
$_ +": "+ $hostname >> "C:\machinenames.txt"
}
else {
$_ +": Cannot resolve hostname" >> "C:\machinenames.txt"
}
}
<#
Find Computer name for set of IP addresses from CSV:
Use the below powershell script to get hostname for multiple IP addresses from
csv file. First create the csv file ip-addresses.csv which includes the column
IPAddress in the csv file. You will get the hostname and IP address list in the
csv file machinenames.csv.
#>
Import-Csv C:\ip-Addresses.csv |
ForEach-Object{
$hostname = ([System.Net.Dns]::GetHostByAddress($_.IPAddress)).Hostname
if($? -eq $False){
$hostname="Cannot resolve hostname"
}
New-Object -TypeName PSObject -Property @{
IPAddress = $_.IPAddress
HostName = $hostname
}
} |
Export-Csv 'D:\Temp\machinenames.csv' -NoTypeInformation -Encoding UTF8
还有一个非常简单的 cmdlet Resolve-DnsName
。
Resolve-DnsName 10.1.1.1
结果有很多细节。 NameHost
是您想要的:
