Exempel

I följande kodexempel visas anycast-adresserna för nätverksgränssnitten på den lokala datorn.

Kommentarer

En anycast-adress identifierar flera datorer. Paket som skickas till en anycast-adress skickas till någon av datorerna som identifieras av adressen. Anycast-adressering är en IPv6-funktion som används för att uppdatera routertabeller för en grupp värdar.
