Perso, sur chaque installation de Windows 10, je désactive tous les mécanismes de transition vers IPv6 :
- ISATAP
- Teredo
- 6to4
Via un script qui permet d'afficher l'état de ces protocoles et de les désactiver :
@ECHO OFF
CLS
:MENU
ECHO.
ECHO ...............................................
ECHO PRESS 1, 2 OR 3 to select your task, or 4 to EXIT.
ECHO ...............................................
ECHO.
ECHO 1 - Get Teredo Status
ECHO 2 - Disable Teredo
ECHO 3 - Enable Teredo
ECHO 4 - EXIT
ECHO.
SET /P M=Type 1, 2, 3, or 4 then press ENTER:
IF %M%==1 GOTO STATUS
IF %M%==2 GOTO DISABLE
IF %M%==3 GOTO ENABLE
IF %M%==4 GOTO EOF
:STATUS
netsh interface teredo show state
netsh interface isatap show state
netsh interface 6to4 show state
GOTO MENU
:DISABLE
netsh int ipv6 isatap set state disabled
netsh int ipv6 6to4 set state disabled
netsh interface teredo set state disable
GOTO MENU
:ENABLE
netsh interface teredo set state enable
GOTO MENU
