isc-dhcp is EOL. I'd suggest using kea-dhcp from the same ISC. I believe there could be a script or some kind of migration path from isc-dhcp to Kea. I've been using Kea in production with no problems.

I really wish there was a better option for a Linux DHCP server. At my past job we were using isc-dhcp and it was absolutely horribly showing it's age (md5 api "keys", bespoke socket-based API "protocol", most things impossible to do via the "API", clustering that didn't really work, etc.). Kea is barely an improvement, with oddities such as being written in C++ and requiring recompiling for plugins, or an extremely weird API. It's obvious is still written by the same old folks who have no idea how software is supposed to work in the 2020s.

We need something modern - easy clustering, modern API, event stream, gRPC-based plugins, etc. (And yes, I have thought about developing it myself, it's on my pile of TODO)

One remark. Kea doesn't have some of functionalities provided by ISC-DHCP. If you use a lot of dhcp-eval and make decisions based on different dhcp options content kea is still a no-go since there is no workarround. Usually at ISP level dhcp is one puzzle of much more complicated system.

I tried if few times and every time I stuck on something and messagefrom developers was: this isc-dhcp feature is not supported. This was huge national scale ISP and bypassing those limitations means a lot of $ to adapt surrounding systems providing input to isc-dhcp LDAP DB in its own config style.
