Command to find network interface for IP

Christopher Duran |

With ipconfig I can show the list of network adapters and their settings, e.g. the IP address.

I'm looking for a reverse command that displays the name of the network adapter for a given IP address.

I have tried filtering the output of ipconfig with a command like ipconfig | find "192.168.2.4" but then the adapter name is gone.

My output of ipconfig is (the tricky part seems that I have several addresses on one adapter here):

Windows IP Configuration

How do I display the name of a network adapter for a given IP address?

This solution does not require any external commands (pcre2grep, sed, etc).

Use the following batch file (getname.cmd):

@echo off
setlocal
setlocal enabledelayedexpansion
set "_adapter="
set "_ip="
for /f "tokens=1* delims=:" %%g in ('ipconfig /all') do ( set "_tmp=%%~g" if "!_tmp:adapter=!"=="!_tmp!" ( if not "!_tmp:IPv4 Address=!"=="!_tmp!" ( for %%i in (%%~h) do ( if not "%%~i"=="" set "_ip=%%~i" ) set "_ip=!_ip:(Preferred)=!" if "!_ip!"=="%1" ( @echo !_adapter! ) ) ) else ( set "_ip=" set "_adapter=!_tmp:*adapter =!" )
)
endlocal

Usage:

getname ipaddress

Example:

F:\test>getname 192.168.42.78
Local Area Connection 2
F:\test>

You could use this PS one liner: 

$addr='192.168.2.4'; get-wmiobject Win32_NetworkAdapterConfiguration |? {$_.ipaddress -contains $addr} |select Description |% {$_.Description}

To use it directly from command line: 

powershell "$addr='192.168.2.4'; get-wmiobject Win32_NetworkAdapterConfiguration |? {$_.ipaddress -contains $addr} |select Description |% {$_.Description}"

or if you want to reuse it put it in a script and make the address a parameter

Edit: to get a name as it shows in Win/Ipconfig: 

$addr='192.168.2.4';
$netconf = get-wmiobject Win32_NetworkAdapterConfiguration |? {$_.ipaddress -contains $addr};
$netconf |% {$_.GetRelated("win32_NetworkAdapter")} | select NetConnectionID |%{$_.NetConnectionID}

(the assignment to intermediary variables is only to make it a bit more readable)

I'm looking for a reverse command that displays the name of the network adapter for a given IP address.

Based on everything I tried, this should work seems you say you need to get this information ONLY from the IP address which you already specify in your example.

INTERACTIVE PROMPT FOR IP ADDRESS TO GET NETWORK CONNECTION NAME

(Use WMIC and some batch FOR loop token and delim parsing to get the network connection name for a specified IP address.)

(The result value will echo to a command window and a message box window. It's all batch script but dynamically builds some VBS script functions to simplify the process for anyone that needs.)

@ECHO ON
:SetTempFiles
SET tmpIPaddr=%tmp%\~tmpipaddress.vbs
SET tmpNetConName1=%tmp%\~tmpNetConName1.txt
SET tmpNetConName2=%tmp%\~tmpNetConName2.txt
SET tmpBatFile=%tmp%\~tmpBatch.cmd
SET tmpVBNetCon=%tmp%\~tmpVBNetCon.vbs
IF EXIST "%tmpIPaddr%" DEL /F /Q "%tmpIPaddr%"
IF EXIST "%tmpNetConName1%" DEL /Q /F "%tmpNetConName1%"
IF EXIST "%tmpNetConName2%" DEL /Q /F "%tmpNetConName2%"
IF EXIST "%tmpBatFile%" DEL /Q /F "%tmpBatFile%"
IF EXIST "%tmpVBNetCon%" DEL /Q /F "%tmpVBNetCon%"
:InputBox
SET msgboxTitle=IP ADDRESS
SET msgboxLine1=Enter the IP address to get its Windows connection name
>"%tmpIPaddr%" ECHO wsh.echo inputbox("%msgboxLine1%","%msgboxTitle%")
FOR /F "tokens=*" %%N IN ('cscript //nologo "%tmpIPaddr%"') DO CALL :setvariables %%N
GOTO EOF
:setvariables
SET IPAddress=%~1
FOR /F "USEBACKQ TOKENS=3 DELIMS=," %%A IN (`"WMIC NICCONFIG GET IPADDRESS,MACADDRESS /FORMAT:CSV | FIND /I "%IPAddress%""`) DO (SET MACAddress=%%~A)
FOR /F "USEBACKQ TOKENS=3 DELIMS=," %%B IN (`"WMIC NIC GET MACADDRESS,NETCONNECTIONID /FORMAT:CSV | FIND /I "%MACAddress%""`) DO ECHO(%%~B>>"%tmpNetConName1%"
::: Parse Empty Lines
FINDSTR "." "%tmpNetConName1%">"%tmpNetConName2%"
::: Build Dynamic Batch with ECHO'd Network Connection Value
FOR /F "tokens=*" %%C IN (%tmpNetConName2%) DO ECHO ECHO %%~C>>"%tmpBatFile%"
IF NOT EXIST "%tmpBatFile%" GOTO :NullExit
START "" "%tmpBatFile%"
::: Build Dynamic VBS with Message Box Network Connection Value
FOR /F "tokens=*" %%C IN (%tmpNetConName2%) DO (SET vbNetconName=%%~C)
ECHO msgbox "%vbNetconName%",0,"%vbNetconName%">"%tmpVBNetCon%"
START /B "" "%tmpVBNetCon%"
EXIT /B
:NullExit
ECHO msgbox "Cannot find MAC Address, check to confirm IP Address was correct.",0,"Invalid IP">"%tmpVBNetCon%"
START /B "" "%tmpVBNetCon%"
EXIT /B

ALL ONE-LINERS

NATIVE WINDOWS ONLY WITH NETSH ALL INTERFACES (ALL IPv4 ADDRESSES)

NETSH INT IP SHOW CONFIG | FINDSTR /R "Configuration for interface.* Address.*[0-9][0-9]*\.[0-9][0-9]*\.[0-9][0-9]*\.[0-9][0-9]*"

enter image description here

NATIVE WINDOWS ONLY WITH IPCONFIG ALL INTERFACES (ALL IPv4 ADDRESSES)

IPCONFIG | FINDSTR /R "Ethernet* Address.*[0-9][0-9]*\.[0-9][0-9]*\.[0-9][0-9]*\.[0-9][0-9]*"

enter image description here

USING PCRE2GREP (per @SalvoF)

SINGLE IP ADDRESS SPECIFIED

netsh interface ipv4 show address | pcre2grep -B2 "192\.168\.2\.4" | FIND /V "DHCP"

FIND ALL IP ADDRESSES 

netsh interface ip show config | pcre2grep -B2 ^(?:[0-9]{1,3}\.){3}[0-9]{1,3}$ | FIND /V "DHCP" | FIND /V "Gate" | FIND /V "Metric" | FIND /V "Subnet"

FIND ALL IP ADDRESSES (Cleaned Up Regex (per @SalvoF)) 

netsh interface ip show config | pcre2grep "^[A-Z]|IP.*([0-9]{1,3}(\.|)){4}"

Please note that the pcre2grep I tried is per @SalvoF [+1] as he suggested but using the.... FIND /V to remove the line above containing DHCP seems to get the desired output as you described. I used NETSH rather than IPCONFIG as well.

To be more accurate, following OP's example, I'd use sed, which can be found under the \usr\local\wbin folder of this zipped file (UnxUtils project).

ipconfig | sed -rn "/^[A-Z]/h;/192.168.2.4/{g;s/.* adapter (.*):/\1/p;}"

-n suppresses non matching lines; first pattern finds any line starting with capital letter, then h puts it away on hold space; second match is on wanted IP number: at this point, line holding interface name is recalled (g), extra leading text stripped (s), and printed (p).

Just for the record, here's another batch solution, it exploits delayed expansion of the %ERRORLEVEL% system variable:

@echo off
setlocal EnableDelayedExpansion
for /f "delims=" %%L in ('ipconfig') do ( echo %%L | findstr /r "^[A-Z]" 1>NUL if !errorlevel! == 0 set "_int=%%L" echo %%L | findstr /c:%1 1>NUL if !errorlevel! == 0 ( set "_int=!_int::=!" echo !_int:* adapter =! goto:eof )
)

It can be invoked this way: find_int.cmd 192.168.1.100

Thanks for the effort everyone. It seems there are several hurdles:

  • the number of IP addresses assigned to an adapter
  • the language of the OS

All the -Bx and Regex stuff seems to break easily, so I googled for something I could implement myself and came up with the following C# program, which takes the IP address as parameter (IP2Adapter <IP>):

using System;
using System.Net.NetworkInformation;
using System.Net.Sockets;
namespace IP2Adapter
{ class Program { static void Main(string[] args) { var adapters = NetworkInterface.GetAllNetworkInterfaces(); foreach (var adapter in adapters) { var ipProps = adapter.GetIPProperties(); foreach (var ip in ipProps.UnicastAddresses) { if ((adapter.OperationalStatus == OperationalStatus.Up) && (ip.Address.AddressFamily == AddressFamily.InterNetwork)) { if (ip.Address.ToString() == args[0]) Console.Out.WriteLine(adapter.Name); } } } } }
}

On Windows 10 Powershell, this can be achieved with the following:

Get-NetIPAddress -IPAddress '192.168.2.4' | %{$_.InterfaceAlias};

This will give a result such as Wi-Fi.

Where You can substitute InterfaceAlias for any other object property.

To get all properties, simply omit the pipes, and run: Get-NetIPAddress -IPAddress '192.168.2.4'.

Other network adapter related properties (such as Description) can usually be queried based on InterfaceAlias or InterfaceIndex, eg.:

Get-NetAdapter -InterfaceAlias Wi-Fi | %{$_.InterfaceDescription};

Which will give something like: Intel(R) Dual Band Wireless-AC 8265.
