Dnsmasq provides network infrastructure for small networks: DNS, DHCP, router advertisement and network boot. It is designed to be lightweight and have a small footprint, suitable for resource constrained routers and firewalls.
It's simple configuration and lightweight nature makes it a perfect fit for a homelab DNS from a low-powered device like a Raspberry.
