How to get the IP Address for your Local Area Connection on Windows Server?

  • 772

I want to create a batch or vbs file that will put together a url and executed. Part of that url needs to be the actual ip address of the machine. How I am able to get that IP address in a variable to include it on the script?

EDIT 1:

I found out that the command below will give me the IP Address, but still don't know how to get that value into a variable to use it in a script.

c:\> wmic NICCONFIG WHERE IPEnabled=true GET IPAddress /format:csv

Node,IPAddress
IP-0AFB,{10.25.5.2}
windows scripting windows-server-2003 wmi ip

  1. Here's some sample code I used in a previous script...

    Dim myIPAddress : myIPAddress = ""
Dim objWMIService : Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\cimv2")
Dim colAdapters : Set colAdapters = objWMIService.ExecQuery("Select IPAddress from Win32_NetworkAdapterConfiguration Where IPEnabled = True")
Dim objAdapter
For Each objAdapter in colAdapters
  If Not IsNull(objAdapter.IPAddress) Then myIPAddress = trim(objAdapter.IPAddress(0))
  exit for
Next

Wscript.echo "My IPAddress is " & myIPAddress

  2. If you want to return the IP address into a variable, you could do the following:

    Const wbemFlagReturnImmediately = &h10
Const wbemFlagForwardOnly = &h20
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2")
Set colItems = objWMIService.ExecQuery("SELECT * FROM Win32_NetworkAdapterConfiguration WHERE IPEnabled='TRUE'", "WQL", wbemFlagReturnImmediately + wbemFlagForwardOnly)
For Each objItem In colItems
            strIPAddress = Join(objItem.IPAddress, ",")
            *yourFunctionName*(strIPAddress)
Next

    This code is taken straight from the Scriptomatic v2.0 from Microsoft's TechNet Scriptcenter. Found here: http://technet.microsoft.com/en-us/scriptcenter/dd939957.aspx

  3. Here is a way to extract the WMIC results into a variable in a cmd script:

    @echo off
setlocal
set varcounter=0
set wmicmd="wmic NICCONFIG WHERE IPEnabled=true GET IPAddress"
for /f "tokens=1 delims={, skip=1" %%a in ('%wmicmd%') do call :SETVAR %%a
endlocal
goto :eof

:SETVAR
set /a varcounter=%varcounter% + 1
if not {%1}=={} (
    echo NIC %varcounter% address is {%1}
    set NIC%varcounter%=%1
)
goto :eof

    Notice that since there may be multiple NICs, we have to loop through WMIC's output, which is accomplished by calling :SETVAR for each line of WMIC output (skipping the first one, though, and testing for any blank trailing lines. A variable is created for each enabled NIC found - the variables will be %NIC1%, %NIC2%, etc.

    Line 12, starting with "echo NIC", can be removed once you have it working to your satisfaction.

  4. You know, to make this REALLLLLY useful, I added /node:%1 (to get IP of remote computer) Saves some legwork for system admins & network admins vs. ping or nslookup. I'm sure the other thing I will add is 'error-checking' so that, IF the system happens to not be available, the script can "log that info" - like System %1 not available - and then move on to grab the ip of the next system.

    Often, I make a 'bat' to 'call a bat' So, I would just create a batch file maybe like "getall.bat" below:

    Then just run it like this: getall > getall-log.txt 2>&1

    (Above will pipe out all the info to a text file, including any errors encountered)

    getall.bat

    rem getall.bat
call getnic.bat workstation1
call getnic.bat workstation2
call getnic.bat server1
call getnic.bat server2
rem end of getall.bat

    getnic.bat

    rem - getnic.bat
@echo off
setlocal
set varcounter=0
set wmicmd="wmic /node:%1 NICCONFIG WHERE IPEnabled=true GET IPAddress"
for /f "tokens=1 delims={, skip=1" %%a in ('%wmicmd%') do call :SETVAR %%a
endlocal
goto :eof

:SETVAR
set /a varcounter=%varcounter% + 1
if not {%1}=={} (
    echo NIC %varcounter% address is {%1}
    set NIC%varcounter%=%1
)
goto :eof
rem end of getnic.bat

  5. Converted for IPv6

    @echo off
setlocal
set varcounter=0
set wmicmd="wmic NICCONFIG WHERE IPEnabled=true GET IPAddress"
for /f "tokens=2 delims={, skip=1" %%a in ('%wmicmd%') do call :SETVAR %%a
endlocal
goto :eof

:SETVAR
set /a varcounter=%varcounter% + 1
if not {%1}=={} (
    echo NIC %varcounter% IPv6 address is {%1}
    set NIC%varcounter%=%1
)
goto :eof

  6. I know you asked for a VBS or Batch style script but I thought I would add a PowerShell snippet as well if you wanted to try that route or for anyone else looking at this question...

    [System.Net.Dns]::GetHostAddresses([System.Net.Dns]::GetHostName()) | foreach {write $_.IPAddressToString}

    This will return all IP Addresses currently assigned to the machine.
