You can control access to the printer by using IP addresses. You can set whether to allow for setting or printing from a specified IP address.
IP filtering is disabled by factory default.
An incorrect entry of an IP address does not allow for access to the printer by using the IP protocol. Use care when setting.
If IP filtering is enabled, IPv6 communication is not available.
You can set this setting with the Web page.
The description below uses the following environment as an example.
Printer: B432dn
IP address of the printer: 192.168.0.2
About the IP Address of the printer
How to log in to the Web page
If IP filtering is set to [Enable], access from a host with any IP address other than the ranges that are set in [STEP2] is not allowed.
Enter a range of hosts that are allowed to print or set by using IP addresses.
Use one-byte numbers that are separated with "." to specify an IP address.
If you enter 0.0.0.0 for an IP address, the IP Filtering function is disabled.
If IP address ranges overlap, the address range with the higher [Priority] is given priority.
Regardless of the specifications in [STEP2], you can set the addresses of the administrators who are allowed to print or set in [STEP3].
To correct an IP address range, enter corresponding IP addresses, and then click [Address Range Bar Display/Refresh] again.
If you access the printer through a proxy or other device, the address of the device through which you access the printer is displayed in [Your Current Local Host/Proxy IP Address]. For this reason, your host address may be different from the address that is displayed in [Your Current Local Host/Proxy IP Address].
If nothing is registered in [Administrator's IP Address setting], access to the printer may not be allowed depending on the settings in [STEP2].
If you do not want to register the administrator's IP address, leave the [Administrator's IP Address setting] field blank.
If you enter the administrator's IP address in [Administrator's IP Address setting], the administrator can set from the host of the IP address that is set in [Administrator's IP Address setting] even if you set incorrect settings in [STEP2].
The settings are saved to the printer, and the network function restarts.
