A hostname, such as www.example.com, identifies a website or host on the internet. IP addresses are assigned to host names.

Sometimes you may need to get an IP address from the hostname or vice-versa. It can be easily done with the help of PowerShell.

This tutorial will teach you to resolve the IP address from hostname or vice-versa using PowerShell.

Use the Resolve-DnsName Cmdlet to Resolve IP Address From Hostname With PowerShell

The Resolve-DnsName cmdlet performs a DNS name query resolution for the specified name.

The following command resolves a hostname delftstack.com.

Resolve-DnsName delftstack.com

Output:

Name                                           Type   TTL   Section    IPAddress
----                                           ----   ---   -------    ---------
delftstack.com                                 A      60    Answer     3.6.118.31
delftstack.com                                 A      60    Answer     3.6.18.84

As you can see, it prints other information along with the IP address. To get only IP addresses, use the following command.

(Resolve-DnsName delftstack.com).IPAddress

Output:

To resolve a hostname from the IP address, you can specify an IP address to the command.

Resolve-DnsName 3.6.118.31

Output:

Name                           Type   TTL   Section    NameHost
----                           ----   ---   -------    --------
31.118.6.3.in-addr.arpa        PTR    300   Answer     ec2-3-6-118-31.ap-south-1.compute.amazonaws.com

Use the Dns.GetHostAddresses Method to Resolve IP Address From Hostname With PowerShell

The GetHostAddresses method of Dns Class displays the IP addresses of the specified host.

The following example returns the IP addresses of the host delftstack.com.

[System.Net.Dns]::GetHostAddresses('delftstack.com')

Output:

Address            : 1410467331
AddressFamily      : InterNetwork
ScopeId            :
IsIPv6Multicast    : False
IsIPv6LinkLocal    : False
IsIPv6SiteLocal    : False
IsIPv6Teredo       : False
IsIPv4MappedToIPv6 : False
IPAddressToString  : 3.6.18.84

Address            : 527828483
AddressFamily      : InterNetwork
ScopeId            :
IsIPv6Multicast    : False
IsIPv6LinkLocal    : False
IsIPv6SiteLocal    : False
IsIPv6Teredo       : False
IsIPv4MappedToIPv6 : False
IPAddressToString  : 3.6.118.31

It displays additional information like Address, AddressFamily, ScopeID, and others. To print only IP addresses, run the command below.

[System.Net.Dns]::GetHostAddresses('delftstack.com').IPAddressToString

Output:

The GetHostEntry method resolves a hostname from the IP address.

[System.Net.Dns]::GetHostEntry('3.6.118.31')

Output:

HostName                                        Aliases AddressList
--------                                        ------- -----------
ec2-3-6-118-31.ap-south-1.compute.amazonaws.com {}      {3.6.118.31}

We hope this tutorial gave you an idea to resolve an IP address from the hostname or vice-versa in PowerShell.

In this article, we find out how to use PowerShell to read a list of IP addresses from a text file and resolve them to hostnames and then export to a CSV file for further reviewing.

A lot of systems like Windows Event logs, Firewall logs or IIS logs etc will store the connection information with IP addresses. Barely looking at the IP address may not give a good idea of what systems are connecting and resolving them to hostnames is much easier to process the data. The script that we are going to discuss will read a list of IP addresses from a text file, resolves them to hostnames, and finally exports them to CSV file.

We are going to use [System.Net.DNS] DotNet class for this purpose. The GetHostbyAddress() method available in this class will help us in resolving names to IP addresses.

Code

[CmdletBinding()]
param(
    [Parameter(Mandatory=$True)]
    [string[]]$IPAddress,
    [switch]$ExportToCSV
)

$outarr = @()
foreach($IP in $IPAddress) {
    $result = $null
    try {
        $Name = ([System.Net.DNS]::GetHostByAddress($IP)).HostName
        $result = "Success"

    } catch {
        $result = "Failed"
        $Name="NA"
    }

    $outarr += New-Object -TypeName PSObject -Property @{
        IPAddress = $IP
        Name = $Name
        Status = $result
    } | Select-Object IPAddress, Name, Status
}

if($ExportToCSV) {
    $outarr | export-csv -Path "c:\temp\iptoname.csv" -NoTypeInformation
} else {
    $outarr
}

Some of the readers of my blog might ask why to use GetHostbyAddress method when Resolve-DNSName can do the task. It is simple; the .Net method works from most of the windows computers in use today, including Windows XP. Using Resolve-DNSName requires you to run from Windows8/Windows Server 2012 or above computers. However, use Resolve-DNSName where you can, because it is simply the latest and lets you query other types of records too. The .Net method lets you query A, AAA and PTR records only.

Usage

You can use this script by passing list of IP addresses to -IPAddress parameter as shown below. The Name column indicates the name the ip resolved to, and the Status column contains whether name resolution is successful or not.

.\Resolve-IpToName.ps1 -IPAddress 69.163.176.252,98.137.246.8

You can input the list of IPAddress using text file as well.

.\Resolve-IpToName.ps1 -IPAddress (get-content c:\temp\ips.txt)

By default, the script shows the output on the screen. If you want to export them to CSV, use -ExportToCSV switch.

.\Resolve-IpToName.ps1 -IPAddress (get-content c:\temp\ips.txt) -ExportToCsv

Above CSV file gets generated when you use -ExportToCSV switch.

Hope you find this article useful. Please write in the comment section if you are looking for additional functionality. We will try to make it on the best effort basis.

Using Resolve-DnsName Cmdlet

To retrieve the hostname from the given IP address in PowerShell, use the Resolve-DnsName cmdlet with -Type and PTR parameters.

In this example, the Resolve-DnsName cmdlet resolves the IP addresses to DNS names (hostnames). The -Type parameter is used to specify that the query should be for a PTR record (a PTR record is a type of Domain Name System record that maps an IP address to a hostname), and the -Name parameter specified the IP address we want to resolve.

The command then pipes the output to the Select-Object cmdlet to expand the NameHost property, which contains the hostname corresponding to the IP address. The output is then piped to the Select-Object cmdlet to expand the NameHost property, which contains the hostname corresponding to the IP address.

Replace the 8.8.8.8 with the IP address you want to resolve.

Using nslookup Command

Use the nslookup to get hostname from IP address in PowerShell.

This code used the nslookup command to request the DNS server for the hostname associated with the IP address 213.133.127.245. The nslookup command output is piped to the Select-String cmdlet, which searches for lines containing the Name:, which includes the hostname information.

Using [System.Net.Dns]::GetHostByAddress Method

Use the [System.Net.Dns]::GetHostByAddress method to get hostname from IP address in PowerShell.

We can observe the above code retrieved the hostname of a given IP address. In this example, the $ipAddress variable contained the IP address we wanted to resolve. The [System.Net.Dns]::GetHostByAddress method used this $ipAddress variable as an input and returned the System.Net.IPHostEntry object that contains various details about the host. Once this object is returned, the .HostName property of the IPHostEntry object extracts the hostname.

That’s all about how to get hostname from IP address in PowerShell.
