IPv6 Management Security Features Authorized IP Managers for IPv6 Conversely, in a mask, a "0" binary bit means that either the "on" or "off" setting of the corresponding IPv6 bit in an authorized address is valid and does not have to match the setting of the same bit in the specified IPv6 address.

IPv6 Management Security Features
Authorized IP Managers for IPv6
Conversely, in a mask, a “0” binary bit means that either the “on” or “off” setting
of the corresponding IPv6 bit in an authorized address is valid and does not
have to match the setting of the same bit in the specified IPv6 address.
Figure 6-2 shows the binary expressions represented by individual hexadeci-
mal values in an
ipv6-mask
parameter.
