18 Configure the Adapter for Your EtherNet/IP Network
Two bits of the Class B host ID have been used to extend the net ID. Each unique
combination of bits in the part of the Host ID where subnet mask bits are 1
specifies a different logical network.
The new configuration is:
A second network with Hosts D and E was added. Gateway G2 connects
Network 2.1 with Network 2.2.
Hosts D and E use Gateway G2 to communicate with hosts not on Network 2.2.
Hosts B and C use Gateway G to communicate with hosts not on Network 2.1.
When B is communicating with D, G (the configured gateway for B) routes the
data from B to D through G2.
Use the Rockwell
BootP/DHCP Utility The Rockwell BootP/DHCP utility is a stand alone program that incorporates
the functionality of standard BootP/DHCP software with a user-friendly

installation CD. The module must have DHCP enabled (factory default and the
network address switches set to an illegal value) to use the utility.
To configure your module using the BootP/DHCP utility, perform the following
steps:
1. Run the BootP/DHCP software.
