Duplicate IP Address Detection While connected to your network, the EGX publishes its IP address. To
avoid any duplicate IP address conflicts, the EGX uses the Address
Resolution Protocol (ARP) to see if any other device on your network is
using the same IP address. Table 3 below explains how the EGX handles a
duplicate IP address when it is detected.
