An open-source utility that serves both DHCP and DNS requests concurrently.

If you are an automation engineer or industrial technician, you know the frustration of setting up IP addresses on out-of-the-box EtherNet/IP modules like the 1756-ENBT, 1756-EN2T, or Point I/O adapters. Rockwell’s utility is designed to handle this, but it is notorious for compatibility glitches on modern operating systems.

Open your terminal on a Debian/Ubuntu system and run:

A “better” server in this context meant one that crashed less, handled more concurrent requests (think 100+ diskless terminals booting simultaneously), and offered simple access control.

Finding the root cause of a provisioning failure is incredibly difficult due to primitive text-logging systems. Top Modern Alternatives to Legacy BOOTP/DHCP Servers

This software performs periodic scans of the network, detects new devices broadcasting BOOTP requests, and allows the user to manually assign and "disable" the BOOTP/DHCP functionality once a permanent IP is set. While this tool might be the "version 23" you are looking for (perhaps confusing the version 2.3.0 with "23"), it serves a specific, invaluable purpose. For a "better" experience than just downloading an old .exe from a random site, you should check the official Rockwell Automation knowledgebase for the latest compatible version for your OS.
