Object
column INET-ADDRESS-MIBInetAddress
The group address which, when combined with the
corresponding value of ipMcastScopeNameAddressPrefixLength,
identifies the group range associated with the multicast
scope. Scoped IPv4 multicast address ranges must be
prefixed by 239.0.0.0/8. 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 scope
FF0x::/16 implies an identical scope name for these other
prefixes. No separate FF1x::/16 or FF3x::/16 entries exist
in this table.
This address object is only significant up to
ipMcastScopeNameAddressPrefixLength bits. The remaining
address bits are set to 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.
