Il significato delle ScopeId modifiche varia a seconda del contesto in cui viene usato.The meaning of ScopeId changes depending on the context in which it is used.

• Indirizzo locale del collegamento.Link-local address. In un host con più interfacce connesse a collegamenti distinti, è possibile assegnare lo stesso indirizzo locale del collegamento a più interfacce.On a host with multiple interfaces connected to separate links, the same link-local address can be assigned to multiple interfaces. Per eliminare questa ambiguità, viene usato un identificatore di ambito per specificare l'interfaccia su cui vengono scambiati i messaggi.To eliminate this ambiguity, a scope identifier is used to specify the interface over which messages are exchanged.

• Indirizzi locali rispetto al sito.Site-local addresses. Un host può essere connesso a più siti.A host can be connected to multiple sites.
