DHCP is the more advanced and flexible protocol that we use today. It builds upon and extends BOOTP, acting as its natural successor. DHCP shares the same underlying message format and uses the same UDP ports (67 and 68), which is why many BOOTP and DHCP servers can handle both protocols simultaneously. Unlike BOOTP, DHCP introduces the concept of a "lease," meaning IP addresses are assigned to devices for a specific period. This dynamic allocation is what makes it the standard for modern networks, efficiently managing IP addresses and drastically simplifying network administration.
Developed by the Internet Systems Consortium (ISC), Kea DHCP is the modern successor to the classic ISC DHCP server. It is designed for high-performance, cloud-native, and enterprise environments.
No major industry-standard DHCP server (like ISC DHCP, Microsoft’s, or Cisco’s) has a canonical “2.3” release. However, the Linux/Unix world had bootpd (part of the CMU networking suite) and early ISC DHCP versions. ISC DHCP v2.0 was released in 1997, and hypothetical incremental updates (2.1, 2.2, 2.3) would have appeared around 1998-1999. What made version 2.x “better” than version 1?
If you truly want a better experience, here are the best modern alternatives that support BOOTP, are actively maintained, and outperform the legacy version 23. bootp dhcp server 23 download better
The original BOOTP had no authentication. Any client on the wire could request an IP. A “better” modern server adds:
This is critical if you have legacy devices or diskless stations.
Fortunately, there are for industrial hardware. The Evolution of BOOTP DHCP Server 2.3 DHCP is the more advanced and flexible protocol
: Connect your laptop directly to the device (a crossover or straight patch cable usually works). Look for the MAC address appearing in the "Request History" pane.
BOOTP DHCP Server v23 treats BOOTP requests with the same priority as DHCP requests, allowing mixed environments to function seamlessly.

If you need to assign IP addresses to industrial control devices (PLC, HMI, Drives) in 2026, these are the top recommended alternatives: 1. PLC Tools SIM-IPE Ethernet IP Address Explorer
While the is a piece of industrial history, modern tools like the PLC Tools SIM-IPE or software solutions like Open DHCP Server provide a much "better" experience for modern network commissioning.
Run the new server within a isolated VLAN to ensure it properly responds to BOOTP and DHCP requests without conflicting with production traffic.
It integrates perfectly with Active Directory, providing secure dynamic DNS updates and robust failover clustering.
A "Scope" defines the range of IP addresses the server can lease to clients.
