Resolving IP Address from hostname with PowerShell - powershell

Question

I am trying to get the ipaddress from a hostname using Powershell, but I really can't figure out how.
Any help?

Answer 1

You can get all the IP addresses with GetHostAddresses like this:
$ips = [System.Net.Dns]::GetHostAddresses("yourhosthere")
You can iterate over them like so:
[System.Net.Dns]::GetHostAddresses("yourhosthere") | foreach {echo $_.IPAddressToString }
A server may have more than one IP, so this will return an array of IPs.

Answer 2

this is nice and simple and gets all the nodes.
$ip = Resolve-DNSName google.com
$ip
also try inputting an ip instead of a domain name and check out those results too!

Answer 3

Use Resolve-DnsName cmdlet.
Resolve-DnsName computername | FT Name, IPAddress -HideTableHeaders | Out-File -Append c:\filename.txt
PS C:\> Resolve-DnsName stackoverflow.com
Name Type TTL Section IPAddress

Answer 4

You could use vcsjones's solution, but this might cause problems with further ping/tracert commands, since the result is an array of addresses and you need only one.
To select the proper address, Send an ICMP echo request and read the Address property of the echo reply:
$ping = New-Object System.Net.NetworkInformation.Ping
$ip = $($ping.Send("yourhosthere").Address).IPAddressToString
Though the remarks from the documentation say:
The Address returned by any of the Send overloads can originate from a malicious remote computer. Do not connect to the remote computer using this address. Use DNS to determine the IP address of the machine to which you want to connect.

Answer 5

Working one liner if you want a single result from the collection:
$ipAddy = [System.Net.Dns]::GetHostAddresses("yahoo.com")[0].IPAddressToString;
hth

Answer 6

If you know part of the subnet (i.e. 10.3 in this example), then this will grab any addresses that are in the given subnet:
PS C:\> [System.Net.Dns]::GetHostAddresses("MyPC") | foreach { $_.IPAddressToString | findstr "10.3."}

Answer 7

This worked well for my purpose
$ping = ping -4 $env:COMPUTERNAME
$ip = $ping.Item(2)
$ip = $ip.Substring(11,11)

Answer 8

$computername = $env:computername
[System.Net.Dns]::GetHostAddresses($computername) | where {$_.AddressFamily -notlike "InterNetworkV6"} | foreach {echo $_.IPAddressToString }

Answer 9

The Test-Connection command seems to be a useful alternative, and it can either provide either a Win32_PingStatus object, or a boolean value.

Answer 10

You can use this code if you have a bunch of hosts in text file
$a = get-content "C:\Users\host.txt"(file path)
foreach ($i in $a )
{
$i + "`n" + "==========================";[System.Net.Dns]::GetHostAddresses($i)
}

Answer 11

The simplest way:
ping hostname
e.g.
ping dynlab938.meng.auth.gr
it will print:
Pinging dynlab938.meng.auth.gr [155.207.29.38] with 32 bytes of data

Answer 12

try
$address = 'HOST NAME'
Resolve-DnsName $address | Select-Object Name, IPAddress | Export-csv "C:\Temp\CompleteNSLookup.csv" -append -NoType
