# Option Network Interface
Device Management > Configuration > Network > Option Network Interface

The setting values and statuses of the optional network interface can be displayed and set.

Note

- Settings on this page can be changed by the following administrators and users:
  - Machine Administrator
  - Login users
    User authentication is enabled on the device and users are permitted to make changes to administrator's setting items.

## IPv4

Specify whether IPv4 is active or inactive.

Note

- If IPv4 is already in use, the setting cannot be changed from Active to Inactive. For example, if your browser uses IPv4 to connect to the device, Inactive cannot be selected.

### DHCP

Select Active to use the DHCP server to automatically configure the network settings. Select Inactive to manually configure the network settings.

### IPv4 Address

Enter the IPv4 address of the network interface board or wireless LAN interface unit.
At DHCP operation, the address obtained from the DHCP server is used.

### Subnet Mask

Enter the sub-net mask of the network interface board and wireless LAN board. The sub-net mask is a part of the IP address used as a network address.
When using DHCP, the sub-net mask obtained from the DHCP server is used.

### Primary WINS Server

Enter the primary WINS server IP address.
When using DHCP, the primary WINS server address obtained from the DHCP server is used. If the address cannot be obtained from the DHCP server, the primary WINS server address set for the device is used.

### Secondary WINS Server

Enter the secondary WINS server IP address.
The secondary WINS server is used when the primary WINS server is not available to register the device name. When using DHCP, the secondary WINS server address obtained from the DHCP server is used. If the address cannot be obtained from the DHCP server, the secondary WINS server address set for the device is used.

### Default Gateway Address

Enter the default gateway address.
The default gateway address is the IP address of the host or router used as the gateway when communicating (printing or exchanging information) with a computer on another network.
When using DHCP, the default gateway address obtained from the DHCP server is used. If the address cannot be obtained from the DHCP server, the default gateway address set for the device is used.

Note

- When multiple interface boards are installed, the default gateway address is determined as follows:
  When DHCP is active for all interfaces, the default gateway address is obtained from the DHCP server in order of interface priority.
  When both DHCP active and DHCP inactive interfaces are operating, the default gateway address set for the device is used.
- The order of interface priority can be changed from Remote Maintenance (mshell).

### Scope ID

Enter the NetBIOS scope ID you want to set for the network interface board and wireless LAN board, using up to 31 characters.
When using DHCP, the scope ID obtained from the DHCP server is used. If the ID cannot be obtained from the DHCP server, the ID set for the device is used.

### Use the same host name as Ethernet

Select whether to use the same host name as the Ethernet.

### Host Name

Enter the host name you want to set for the network interface board or wireless LAN interface unit, using up to 63 characters. The default is RNP, followed by the MAC address of the active interface board. If you change the name to other than the default, the new name cannot begin with "RNP" or "rnp".

Note

- Hyphens and periods can be used as part of the host name. However, they cannot be used at the start of a host name or entered consecutively ("--" or ".."). Also, hyphens cannot be used at the end of a host name.

## IPv6

Specify whether IPv6 is active or inactive.

Note

- If IPv6 is already in use, the setting cannot be changed from Active to Inactive. For example, if your browser uses IPv6 to connect to the device, Inactive cannot be selected.

### Link-local Address

Displays the link-local address of the network interface board or wireless LAN board.
The link-local address applies only within the local network (local segment) and begins with "fe80::", followed by an identifier generated from the MAC address of the active interface board.

### Stateless Address

Specify the stateless address of the network interface board or wireless LAN board.

#### Stateless Address Autoconfiguration

Specify whether auto-generation of IPv6 addresses is active or inactive.

#### Stateless Address 1 to Stateless Address 5

Displays auto-generated IPv6 addresses.

### Manual Configuration Address

Enter the IPv6 address assigned for the network interface board or wireless LAN board.

Note

- The following addresses cannot be set:
  Link-local addresses, multicast addresses, loopback addresses, IPv4-compatible addresses, and IPv4-mapped addresses

### Manual Configuration Address (prefix length)

Enter the prefix length of the IPv6 address, using a value between 1 and 128. The default is 64.

### DHCPv6

Select Active to use the DHCPv6 server to automatically configure the network settings. Select Inactive to manually configure the network settings.

### DHCPv6 Address

Displays the address obtained from the DHCPv6 server.

### Default Gateway Address

Enter the default gateway address.
The default gateway address is the IPv6 address of the host or router used as the gateway when communicating (printing or exchanging information) with a computer on another network.
If Stateless Address Autoconfiguration is set to Active, the link-local address of the router is set as the default gateway address. If you specify a default gateway address here, that address is used.
The value currently in use appears in parentheses.

Note

- The following addresses cannot be set:
  Site-local addresses, multicast addresses, loopback addresses, IPv4-compatible addresses, IPv4-mapped addresses, and global addresses

## IPv4/IPv6 Detailed Information

### LLMNR, LPR, DIPRINT, IPP, WINS, Bonjour

Specify whether each protocol is active or inactive.

### UPnP Setting

Select whether to enable or disable the UPnP setting.

### DIPRINT/LPD/IPP Timeout

When printing using WSD (Web Services on Devices) or IPP, specify the time the machine waits for job data before canceling the job.
You can specify a timeout period of 30 to 65535 seconds.
The default timeout period is 900 seconds.

### SNMP

Specify whether SNMP is active or inactive for the interface board(s).

## SNMPv1/v2

### SNMPv1,v2 Function

Specify whether to enable or disable SNMPv1 and v2.

Enter the IPv4 address range of the computers to be allowed access to the machine.
Up to four sets of ranges can be entered. Access from addresses not included in these ranges is prohibited.
If specifying less than four sets, set the unspecified ranges to [0.0.0.0] - [0.0.0.0].
To allow access from all computers, set all ranges to [0.0.0.0]- [0.0.0.0].

### IPv6 Access Control Range 1 to Access Control Range 4

Enter the IPv6 address range of the computers to be allowed access to the machine, using the IP address range or a combination of base address and mask.
Up to four sets of ranges or prefixes can be entered. Access from addresses not included in these ranges or prefixes is prohibited.
To specify a range, select Mask, enter the base address, and then enter the mask range in the Mask Length box using a value between 1 and 128.
If specifying less than four sets, set the unspecified ranges to [::] - [::].
To allow access from all computers, set all ranges to [::]- [::].
