Is there a name for mesh networks with nodes that each handle their own DNS, DHCP, and other services?

I’m looking to learn more about what I assume is a subset of mesh networking where each individual node hosts a DNS and DHCP server. Preferably, if one node was operational it could handle all the services the clients expect, but if multiple nodes were up I would like the DNS and other services to be replicated throughout the nodes.

Is there a name for this type of network or a place I could find documentation on best practices? Is it even possible to do this in a decentralized manner without some sort of controller coordinating the synchronization of the data held at each node?

Thanks everyone!
