** DHCP enhancements to FreeRADIUS 3

As part of our contributions to the FreeRADIUS community, Network RADIUS took on the task of overhauling its DHCP support. The result is the same highly flexible and configurable DHCP server, but now easier to configure and outperforms both ISC and Kea DHCP in most common scenarios. And it’s available now, in FreeRADIUS 3.0.22  (

After running a battery of tests against ISC DHCP and Kea, we identified issues with FreeRADIUS that needed to be addressed in order to improve compliance as well as performance.

We like to think that we understand network administrators pretty well. We know that performance is important, but it’s not the only consideration. In FreeRADIUS 3.0.22 we are excited to provide a DHCP server that:
	• Outperforms ISC DHCP and Kea
	• Has the flexibility to adapt to your network rather than the other way around
	• Implements query strategies that are optimized for the most common databases
	• Simplifies data workflow
	• Empowers real time monitoring
In this post, we’ll provide a high-level overview of the changes we made and why, as well as the final performance results.
