Configuring your machine for a network with an Ethernet cable connection (DCP-J715W, MFC-J615W and MFC-J630W only) For more information on DHCP, BOOTP and RARP, see Using DHCP to configure the IP address on page 100, Using BOOTP to configure the IP address on page 102 and Using RARP to configure the IP address on page 101. If you do not have a DHCP/BOOTP/RARP server, the Automatic Private IP Addressing (APIPA) protocol will automatically assign an IP address from the range 169.254.1.0 to 169.254.254.255. For more 2 information on APIPA, see Using APIPA to configure the IP address on page 102. Subnet mask 2 Subnet masks restrict network communication.  Example: Computer1 can talk to Computer2 • Computer1 IP Address: 192.168.1.2 Subnet Mask: 255.255.255.0 • Computer2 IP Address: 192.168.1.3 Subnet Mask: 255.255.255.0 Note 0 denotes that there is no limit to communication at this part of the address. In the above example, we can communicate with any device that has an IP address that begins with 192.168.1.X. Gateway (and router) 2 A gateway is a network point that acts as an entrance to another network and sends data transmitted via the network to an exact destination. The router knows where to direct data that arrives at the gateway. If a destination is located at an external network, the router transmits data to the external network. If your network communicates with other networks, you may need to configure the Gateway IP address. If you do not know the Gateway IP address then contact your Network Administrator. 10

• Computer2
IP Address:
192.168.1.3
Subnet Mask:

In the above example, we can communicate with any device that has an IP address that begins with

Gateway (and router)

A gateway is a network point that acts as an entrance to another network and sends data transmitted via the
network to an exact destination. The router knows where to direct data that arrives at the gateway. If a
destination is located at an external network, the router transmits data to the external network. If your network
communicates with other networks, you may need to configure the Gateway IP address. If you do not know
the Gateway IP address then contact your Network Administrator.
