■ An IPv6 prefix-length creates a mask in which:
• A mask-bit setting set to 1 ("on") requires the corresponding bit in a
packet's IPv6 source/destination address to be the same binary value
as the mask-bit in the matching IPv6 source/destination address.
• A mask-bit setting set to 0 ("off") is used as a wildcard and allows the
corresponding bit in a packet's IPv6 source/destination address to be
either binary value (0 or 1).

Range of IPv4 Addresses Selected
by the Match Criteria
The leftmost 15 bits must match;
the remaining bits are wildcards.
The leftmost 20 bits must match;
the remaining bits are wildcards.
The leftmost 21 bits must match;
the remaining bits are wildcards.
The leftmost 24 bits must match;
the remaining bits are wildcards.
All bits must match.
Range of IPv6 Addresses Selected
by the Match Criteria
The leftmost 64 bits must match;
the remaining bits are wildcards.
the remaining bits are wildcards.
The first 126 bits must match; the
"C" value in the mask allows four
possible combinations (D37C,
D37D, D37E, and D37F) in the last
block of a matching IPv6 address.
All bits must match.
