Hinweise

Eine Anycastadresse identifiziert mehrere Computer. Pakete, die an eine Anycastadresse gesendet werden, werden an einen der Computer gesendet, die von der Adresse identifiziert werden. Anycast-Adressierung ist ein IPv6-Feature, das zum Aktualisieren von Routertabellen für eine Gruppe von Hosts verwendet wird.
