I looked at Kea based on ISC's suggestion to replace their DHCPD. I can totally see deploying this in a data-center environment given how flexible it is but it was just to overwhelming for me for simple home use. I personally found that migrating to dnsmasq for DHCP alone was extremely simple, light weight and most importantly trivial to comprehend. Even with all my static reservations for cameras, routers, laptop, computers and phones my config is only 46 lines long and very easy to read. Migrating to Kea on the other hand required using optional modules and a very lengthy configuration that was entirely too fragile for my use case, but that was just my personal anecdotal experience. I also like the memory footprint of dnsmasq and that I rarely have to think about it.

     Private  +   Shared  =  RAM used Program
    476.0 KiB +  24.5 KiB = 500.5 KiB dnsmasq
