The value of [First Address] for [Multiple Addresses] should be smaller than or
equal to that of [Last Address].
•
If <Apply Settings> is set to 'Off' for both [Permit IPv4 Address] and [Reject IPv4
Address], all IPv4 addresses are permitted.
•
If <Apply Settings> is set to 'Off' for [Permit IPv4 Address] and <Apply Settings> is
set to 'On' for [Reject IPv4 Address], IPv4 addresses that are beyond the specified
range of [Reject IPv4 Address] are permitted.

If the usage of a protocol or print application is not permitted on your device, it
cannot be used even after its IPv4 address is permitted on the machine; on your
device, configure the settings to permit the protocol or print application.
NOTE
This machine logs attempts to gain access from IPv4 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.
