Windows IPv6

IPv6 Interface-Konfiguration anzeigen:

 netsh interface ipv6 show addresses

Windows XP bildet die Interface-ID der IPv6 Adresse basierend auf dem modifizierten EUI-64 Verfahren. Ab Windows Vista wird dazu ein sogenannter „permanant“ randomized identifier verwendet, d.h. die IPv6-Adresse ist nicht mehr direkt aus der MAC-Adresse abgeleitet.

Dieses Verhalten kann per netsh-Befehl abgeschalten werden:

netsh interface ipv6 set global randomize­identifiers=disabled  

netsh interface ipv6 add address InterfaceNameOrIndex IPv6Address [[type=]unicast|anycast]
 [[validlifetime=]Minutes|infinite] [[preferredlifetime=]Minutes|infinite] 
 [[store=]active|persistent]

Beispiel:

netsh interface ipv6 set interface InterfaceNameOrIndex [forwarding=]enabled|disabled] 
 [[advertise=]enabled|disabled] [[mtu=]MTUSize] [[store=]active|persistent]

netsh interface ipv6 add route IPv6Address/PrefixLength InterfaceNameOrIndex 
 [[nexthop=]IPv6Address] [[publish=]no|age|yes] [[validlifetime=]Minutes|infinite]
 [[preferredlifetime=]Minutes|infinite] [[store=]active|persistent]

netsh interface ipv6 add route fec0:0:0:1::/64 "Local Area Connection" publish=yes 
netsh interface ipv6 add route fec0:0:0:2::/64 "Local Area Connection 2" publish=yes

netsh interface ipv6 add route ::/0 "Local Area Connection 3" nexthop=fe80::2aa:ff:fe98:2ab1 
  publish=yes

C:>netsh interface ipv6 show /?

!!! Teredo sendet nur dann IPv6 Pakete, wenn das Ziel ausschließlich über IPv6 erreichbar ist (DNS-Antwort). Bei Dual-Stack angebundenen Hosts wird immer IPv4 verwendet.

Status anzeigen lassen:

 netsh interface ipv6 show teredo

Teredo in Netzen mit Microsoft Active Directory aktivieren:

 netsh interface ipv6 set teredo enterpriseclient

Teredo deaktivieren:

 netsh interface ipv6 set teredo disable
