Http-in get Request IP/Address

How come a simple information as this is not available from this node ?

I have multiple clients in the LAN (hence no need for a rev proxy like nginx), and would like to log the source IP coming onto my node-red server (without having to import the node-red-contrib-http-logger because it is said to be used only for debugging purpose and it's indeed a bit overhead for what I need)

something like msg.req.sourceIP would be handy ....
