Setting the IP Network
Address An EtherNet/IP Communications Auxiliary ships with DHCP enabled. You can
set the network Internet Protocol (IP) address by using:
• the EtherNet/IP node address selection switches,
• a Bootstrap Protocol (BOOTP)/Dynamic Host Configuration Protocol
(DHCP) server (e.g., the Rockwell Automation BOOTP-DHCP Server
Utility, which is included with Rockwell Software’s RSLinx™ Classic
software), OR
• a web browser and MAC scanner software.
EtherNet/IP Node Address Selection Switches
The EtherNet/IP Communications Auxiliary comes with three node address
selection switches that allow the user to select the last octet for the IP address
192.168.1.xxx.
Network Parameter Description
Host Name A host name is part of a text address that identifies the
module. The full text address of a module is:
host_name.domain_name.
Domain Name A domain name is part of a text address that identifies the
domain in which the module resides. The full text address of a
module is: host_name.domain_name. The domain name has a
48-character limit.
Primary DNS Server Address This identifies any DNS servers used in the network. You must
have a DNS server configured if you specify an SMTP server
with a name. The DNS server converts the domain name or
host name to an IP address that can be used by the network.
