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-maskparameter.
