•
If you enter '128' in [Prefix Length], the IPv6 addresses of the machine are not
permitted.

If you want to enter a range of addresses, make sure that the number entered in
[First Address] is less than the number entered in [Last Address].

If the usage of a protocol or print application is not permitted on your device, it
cannot be used even if its IPv6 address is permitted on the machine. Configure the
settings of the device to permit the protocol or print application.
NOTE
This machine logs attempts to gain access from IPv6 addresses that it has been
set to reject. For instructions on how to refer to the access log, see "Viewing the
Network Access Log," on p. 8-24.
