A new addressing scheme for multicast IP with an extended scope field to include access rights. A new addressing scheme for multicast communications is disclosed. A new extended scope field is used which embeds a plurality of hierarchical scopes and associates each scope with access rights. This distinguishes between one-to-many and many-to-many addresses and simplifies administration and security. The invention applies equally to IPv4 and IPv6 address schemes.
