用个goto跳出来就是的

@echo off&setlocal enabledelayedexpansion
for /f "delims=" %%a in ('ipconfig /all') do (
    for /f "tokens=1,2 delims=:" %%b in ("%%a") do (
         set "str=%%b"&set "var=%%c"
         if defined flag if "!str:ip=!" neq "!str!" echo !var:~,1!&goto next
         if "!str:~,-3!" equ "vpn" set "flag=a"
   )
)
:next
pause>nul
