Grab IP Using PowerShell

5 posts in this topic

I'm on a computer running Windows XP with PowerShell installed and I would like to be able to grab the IP address from the output of ipconfig, then place it into a variable that will be used as an argument when executing a program. I use Linux on my home computers, so I would know how to do it with shell scripting, but PowerShell is completely different (it reminds me of Java).

I've gotten as far as storing the output of ipconfig in a variable but I don't know how to "grep" it out of all the ouput since I'm not good with RegEx and then store that string into a variable which will be called upon later.

C:\Documents and Settings\bran>ipconfig

Windows IP Configuration


Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . : domain.net
IP Address. . . . . . . . . . . . : 10.6.16.2
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 10.6.16.1

Ethernet adapter Local Area Connection 2:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.42.24
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.42.129

The IP address that I would like to be able to grab is that of Ethernet adapter Local Area Connection 2, the first three octets are always the same (192.168.42) it is only the last octet that changes.

So in short I would like something along the lines of this:

$ip=ipconfig
echo $ip [grab IP address and store it in a variable]
forcebindip $ipaddress c:\program.exe

or for those of you that understand shell scripting

ipconfig | grep "192.168.42"| head -n1| cut -c 30 > $ip
forcebindip $ip c:\program.exe

Taken from there:

((ipconfig | findstr [0-9].\.)[0]).Split()[-1]

It only retrieve the first ip address if you have more than one network adapter.

Just a quick follow up batch file using ideas from both jaclaz and allen2:

@ECHO OFF & SETLOCAL ENABLEEXTENSIONS

REM Change the line below to reflect your known IP string
SET KIP=192.168.42

FOR /F "TOKENS=2 DELIMS=:" %%# IN ('IPCONFIG^|FINDSTR/I IP.*%KIP:.=\.%\.') DO (
CALL :SUB %%#)
PAUSE
GOTO :EOF

:SUB
ECHO=%*

The SUB currently only shows you the relevant IP Address, you would obviously replace that with the code you wish to run, (and when you're happy REMove the PAUSE).

I don't know if this works on XP or not as I don't have a box at the moment to check, but if XP has the "Get-NetIPAddress" cmdlet, you could start with this and go from there:

Get-NetIPAddress | Sort-Object -Property InterfaceIndex | Format-Table
