TCP/IP
■ Get IP Address
Set whether to automatically acquire or manually specify the information (IP Address, Subnet Mask,
Gateway Address) required for TCP/IP from a DHCP (Dynamic Host Configuration Protocol)
server, a BOOTP server or a RARP server. For details about manually set addresses, consult your
network administrator.
(Default is DHCP server.)
The IP Address setting screen is displayed when DHCP server or BOOTP server is changed to Manual. Manu-
ally set the IP address in this screen.
■ IP Address, Subnet Mask, Gateway Address
These items are used to confirm the automatically acquired address or to manually set addresses.
Enter addresses in the format “xxx.xxx.xxx.xxx”.
Specify the IP address and gateway address within the range 0 to 255. Note, however, that 224 and
225.xxx.xxx.xxx and 127.xxx.xxx.xxx cannot be set.
Specify the subnet mask by a combination of the numbers 0, 128, 192, 224, 248, 252, and 255. Note
that 0 cannot be set in the middle of a subnet mask.
If you do not wish to set the gateway address, enter “0.0.0.0”.
●
When the IP Address is set, the Subnet Mask and Gateway Address can be set.
●
Setting an erroneous IP Address can adversely affect the entire network.
●
Set the Gateway Address only when it must be clearly indicated. The Gateway Address need not be set in envi-
ronments where it is set dynamically.
■ IP Address for Downloading
Set the IP address that is required for downloading software upgrades for this machine by the firm-
ware utility.
Enter addresses in the format “xxx.xxx.xxx.xxx”. xxx stands for any numerical value within the
range 0 to 255. Note, however, that 224 and 225.xxx.xxx.xxx and 127.xxx.xxx.xxx cannot be set.
Setting an erroneous IP Address can adversely affect the entire network.
■ IP Filter
Set whether or not to restrict acceptance of printing from the LPD protocol by the IP address. When
On is set, only printing from registered IP addresses is accepted.
(Default is Off.)
This setting is disabled when the accepted IP Address is not set even if On is set.
For details on setting restricted IP Addresses, see “Chapter 5 Configuring From Computer (CentreWare Inter-
net Services)” in “Part 1 Printer” of the User Guide (Printer/Scanner).
