It's mostly normal for programs to not work without IPv6, but it would be nice to have an option to select IP to listen on.

Sorry about the delay, yes this could be addressed. The server logic is fairly simpe, i think this part needs updating on IPv4 https://github.com/facebookincubator/dynolog/blob/main/dynolog/src/rpc/SimpleJsonServer.cpp#L34-L52
