Trying to get default route info from netstat output, but have no luck. Findstr also accept lines containing string

224.0.0.0

what (by my opinion) does not meet pattern. What am I doing wrong?

Code: Select all

netstat -rn | findstr "0.0.0.0"

BTW: Need to get default route exactly from netstat output for some reason, not by netsh, WMI, PS or any other way.

You should provide more info. Here is the output from my netstat command:

Code: Select all

c:\>netstat -rn|findstr "0.0.0.0"
          0.0.0.0          0.0.0.0      192.168.8.1    192.168.8.108     25
        224.0.0.0        240.0.0.0         On-link         127.0.0.1    331
        224.0.0.0        240.0.0.0         On-link     192.168.8.108    281

So what info do you need?

Try this:

Code: Select all

c:\>netstat -rn|findstr /L /C:" 0.0.0.0"
          0.0.0.0          0.0.0.0      192.168.8.1    192.168.8.108     25

Add space before the first 0. Note /C switch.

You should read viewtopic.php?f=3&t=6108#p38525
Read this too:

Code: Select all

findstr /?

Provide your netstat output and what you want to get.

Code: Select all

You missed what miskox said about putting a space before the first 0 in your findstr command. It should be like this:

Code: Select all

netstat -rn|findstr /L /C:" 0.0.0.0"

Your output is correct because literal string "0.0.0.0" is part of string "240.0.0.0".
Add a space to avoid these false positives.

netstat -rn | findstr /C:" 0.0.0.0"

Thanks all!

Finaly solved by

Code: Select all

netstat -rn | findstr /R "\<0.0.0.0"

, it look to me better than put space as a part of patterns.

BTW: Sorry unattential reading

You can create a batch file in order to get the Default Gateway and the Local IP Address from netstat command

Code: Select all

@echo off
Title Get Default Gateway and Local IP Address from netstat command
@for /f "tokens=3,4 delims= " %%a in ('netstat -rn ^| findstr "\<0.0.0.0"') do ( 
	Set "Gateway=%%a"
	Set "MyIP=%%b"
)
echo( Gateway = %Gateway%
echo( MyIP    = %MyIp%
pause
