中国DOS联盟论坛 » DOS批处理 & 脚本技术（批处理室） » To display the IP under DOS and output it to a file, you can use the following steps: First, use the `ipconfig` command to get the IP information. Then, redirect the output to a file. The typical command would be: ```batch ipconfig | findstr "IPv4 Address" > ip.txt ``` This command runs the `ipconfig` command, pipes its output to `findstr` to filter out the line containing "IPv4 Address", and then redirects the result to a file named `ip.txt`.

I mean,,,

I need to obtain the local machine's IP address, gateway address, and DNS under DOS, and output them to a file while displaying them.

I went to take a look.. It was quite helpful to me....
The problem is that the resulting effect isn't what I wanted.

I just want a single file with only one IP.. like 10.10.1.1, just a simple single line, that's enough.

```@echo off
for /f "delims=: tokens=2" %%i in ('ipconfig ^| findstr /i /c:"ip address"') do echo %%i >ip.txt
```

It doesn't work either... Only one is output.
echo 10.10.1.1
echo fe80 1>ip.txt
echo fe80 1>ip.txt
echo fe80 1>ip.txt
What comes out is fe80... The 10.10.1.1 is not written in.

@echo off
setlocal enabledelayedexpansion
set IP_num=0
set Gateway_num=0
set DNS_num=0
for /f "tokens=2* delims=:" %%i in ('ipconfig /all ^| find /i "IP Address"') do (
for /f "tokens=2* delims=:" %%a in ('ipconfig /all ^| find /i "Default Gateway"') do (
for /f "tokens=2* delims=:" %%1 in ('ipconfig /all ^| find /i "DNS Servers"') do (
set IP_=%%i
set Gateway_=%%a
set DNS_=%%1
if "!IP_num!"=="2" set IP=!IP_:~1!
if "!Gateway_num!"=="0" set Gateway=!Gateway_:~1!
if "!DNS_num!"=="0" set DNS=!DNS_:~1!
set /a IP_num=!IP_num!+1
set /a Gateway_num=!Gateway_num!+1
set /a DNS_num=!DNS_num!+1
)
)
)
(echo External network IP=%IP%
echo.
echo Gateway=%Gateway%
echo.
echo DNS=%DNS%
)>ip.txt

The owner only needs to modify the following three values to get the internal and external network IPs and gateways:
if "!IP_num!"=="2"
if "!Gateway_num!"=="0"
if "!DNS_num!"=="0"
The values following are different, and the extracted IPs are different. Please test by yourself!

In addition, only the first DNS is extracted. Does it meet the owner's requirements?

Thanks for the answer from floor 8, it's great. I've solved the problem.
