How To Perform Reverse DNS Lookup In PowerShell

If you’ve ever wondered how to find the domain name associated with an IP address, you’ll be glad to know that PowerShell provides a convenient solution.

By using a simple script, you can perform a reverse DNS lookup and retrieve the domain name corresponding to an IP address.

In this article, we’ll walk you through the process of performing a reverse DNS lookup in PowerShell.

The PowerShell Script

To get started, here’s the PowerShell script that you can use to perform a reverse IP address lookup:

# Get the IP address to lookup
$ipAddress = "192.168.1.1"

# Perform the reverse DNS lookup
$reverseDnsLookup = Resolve-DnsName -Name $ipAddress -Type PTR

# Print the results
If ($reverseDnsLookup) {
    Write-Host "The reverse DNS lookup for $ipAddress returned the following results:"
    Write-Host "    Host name: $reverseDnsLookup.HostName"
    Write-Host "    PTR record: $reverseDnsLookup.PtrRecord"
}
Else {
    Write-Host "The reverse DNS lookup for $ipAddress did not return any results."
}

Running the Script

To run the script, you’ll need to ensure that you have the DnsServer module installed on your computer.

If you don’t have it, you can install it by running the following command in PowerShell:

Install-Module DnsServer

Once you have the DnsServer module installed, you can proceed to run the script. Save the script as a .ps1 file (e.g., reverse-dns-lookup.ps1) and run it from the command prompt using the following command:

.\reverse-dns-lookup.ps1

Interpreting the Results

When you run the script, it will perform a reverse DNS lookup for the specified IP address and display the results. The output will look similar to this:

The reverse DNS lookup for 192.168.1.1 returned the following results:
    Host name: mycomputer.local
    PTR record: 192.168.1.1

In the example above, the reverse DNS lookup successfully retrieved the host name and PTR record for the IP address 192.168.1.1.

The host name represents the domain name of the computer that owns the IP address, while the PTR record represents the IP address of the computer that owns the domain name.
