先把网卡名称读出来：

@echo off
setlocal enabledelayedexpansion

echo 请选择一个网卡：
set "choice="
set "count=1"
for /f "tokens=1 delims=:" %%a in ('netsh interface ipv4 show addresses ^| findstr "接口"') do (
     set "adapter=%%a"
     set "adapter=!adapter:~4,-5!"
     echo !count!. !adapter!
     set "interface!count!=!adapter!"
     set /a "count+=1"
)
set /p "choice=请输入序号："

rem 获取选定网卡的IP及网关信息
set "interfaceName=!interface%choice%!"
rem echo 已选网卡：!interfaceName!

for /f "tokens=1-2 delims=:" %%i in ('netsh interface ipv4 show config name^="!interfaceName!" ^| findstr /C:"IP 地址"') do (
    set "ip_line=%%j"
    for /f "tokens=*" %%f in ("!ip_line!") do set "ipAddress=%%f"
    echo !interfaceName!-[IP  地址]：!ipAddress!
)

rem 提取已选网卡的默认网关
for /f "tokens=1-2 delims=:" %%i in ('netsh interface ipv4 show config name^="!interfaceName!" ^| findstr /C:"默认网关"') do (
    set "gateway=%%j"
    for /f "tokens=*" %%f in ("!gateway!") do set "gateway=%%f"
    if not "!gateway!"=="" (
        echo !interfaceName!-[默认网关]：!gateway!
    ) else (
        echo 该网卡没有配置默认网关。
    )
)

    试了一下，结果存疑：
