IPv6 Management Security Features

Authorized IP Managers for IPv6

Figure 6-7 shows the bits in the fourth block of the mask that determine the valid subnets in which authorized stations with an IPv6 device ID of 244:17FF:FEB6:D37D reside.

FFF8 in the fourth block of the mask means that bits 3 - 15 of the block are fixed and, in an authorized IPv6 address, must correspond to the “on” and “off” settings shown for the binary equivalent 0000 in the fourth block of the IPv6 address. Conversely, bits 0 - 2 are variable and, in an authorized IPv6 address, may be either “on” (1) or “off” (0).

As a result, assuming that the seventh and eighth bytes (fourth hexadecimal block) of an IPv6 address are used as the subnet ID, only the following binary expressions and hexadecimal subnet IDs are supported in this authorized IPv6 manager configuration:

Authorized Subnet ID in Fourth	Binary Equivalent
Hexadecimal Block of IPv6 Address
0000	0000 0000
0001	0000 0001
0002	0000 0010
0003	0000 0011
0004	0000 0100
0005	0000 0101
0006	0000 0110
0007	0000 0111
