hwIpMcastBoundaryAddress 1.3.6.1.4.1.2011.5.25.149.1.1.1.7.1.3

The group address which, when combined with the corresponding value of hwIpMcastBoundaryAddressPrefixLength, identifies the group range for which the scoped boundary exists. Scoped IPv4 multicast address ranges must be prefixed by 239.0.0.0/4. Scoped IPv6 multicast address ranges are FF0x::/16, where x is a valid RFC 4291 multicast scope. An IPv6 address prefixed by FF1x::/16 is a non-permanently- assigned address. An IPv6 address prefixed by FF3x::/16 is a unicast-prefix-based multicast addresses. A zone boundary for FF0x::/16 implies an identical boundary for these other prefixes. No separate FF1x::/16 or FF3x::/16 entries exist in this table. This address object is only significant up to hwIpMcastBoundaryAddressPrefixLength bits. The remainder of the address bits are zero. This is especially important for this index field, which is part of the index of this entry. Any non-zero bits would signify an entirely different entry. For addresses of type ipv4z or ipv6z, the appended zone index is significant even though it lies beyond the prefix length. Zone index zero is not valid in this table.
