How to get the host or computer name in PowerShell

To get the host name of the computer you are currently working on in PowerShell, you can use the $env:COMPUTERNAME automatic variable. This variable contains the name of the computer as it is known on the network.

Using `$env:COMPUTERNAME` to get the host name

Here's an example of how you might use the $env:COMPUTERNAME variable to get the host name of your computer:

# Get the host name of the current computer
$hostName = $env:COMPUTERNAME

# Print the host name to the screen
Write-Host "The host name of this computer is $hostName"

In this example, the $env:COMPUTERNAME variable is used to get the host name of the current computer, and the value is stored in the $hostName variable. The host name is then printed to the screen using the Write-Host cmdlet.

Using `hostname` to get the host name

Alternatively, you can use the hostname command to get the host name of the current computer.

This command is available in all versions of Windows, and it provides a quick and easy way to get the host name without using a PowerShell variable.

Here's an example of how you might use the hostname command to get the host name of your computer:

# Get the host name of the current computer
hostname

# Print the host name to the screen
Write-Host "The host name of this computer is $(hostname)"

In this example, the hostname command is used to get the host name of the current computer. The output of the hostname command is then printed to the screen using the Write-Host cmdlet. You can also use the hostname command in a pipeline or store the output in a variable for further processing.

How to find the hostname from an IP address in PowerShell

To find the host name of a computer with a specific IP address in PowerShell, you can use the Resolve-DnsName cmdlet. This cmdlet can be used to resolve a host name from an IP address, or vice versa.

Here's an example of how you might use the Resolve-DnsName cmdlet to find the host name of a computer with a specific IP address:

# Find the host name of a computer with a specific IP address
$hostName = Resolve-DnsName -Name 10.0.0.1 -Type A

# Print the host name to the screen
Write-Host "The host name for 10.0.0.1 is $($hostName.NameHost)"

In this example, the Resolve-DnsName cmdlet is used to find the host name of a computer with the IP address 10.0.0.1.

The -Name parameter specifies the IP address to resolve, and the -Type parameter specifies that the IP address is an "A" record (i.e., a standard IPv4 address). The host name is then stored in the $hostName variable and printed to the screen using the Write-Host cmdlet.

Alternatively, you can use the nslookup command to find the host name of a computer with a specific IP address.

Here's an example of how you might use the nslookup command to find the host name of a computer with a specific IP address:

# Find the host name of a computer with a specific IP address
nslookup 10.0.0.1

# Print the host name to the screen
Write-Host "The host name for 10.0.0.1 is $(nslookup 10.0.0.1 | Select-Object -ExpandProperty Name)"

In this example, the nslookup command is used to find the host name of a computer with the IP address 10.0.0.1. The output of the nslookup command is then printed to the screen using the Write-Host cmdlet. You can also use the nslookup command in a pipeline or store the output in a variable for further processing.
