Is it possible to configure Unbound to listen on Unix Domain Socket, instead of tcp/udp port? I use Unbound on my local machine only

JiangHeng12138 commented 2 years ago

The DNS client(dig, nslookup, etc) does not support Unix Domain Socket.

My DNS client (OpenLiteSpeed webserver) does

A use case for that:

Adguard home or Pi-hole asks Unbound via Unix Domain socket instead of a TCP/UDP port, thus killing any possible overhead.

I also have the same idea. When Unbound is used as an upstream for other DNS server programs, this is a very good feature.
