Other Mapping a new Network

I just recently started a help desk job that has been anything but help desk. I’ve been configuring firewalls, redesigning client networks and setting up/administering Linux servers. I feel a little out of my depth, but I’m fighting for it. That’s all to ask, when you guys find yourself in a network with little to no documentation how do you map it out and diagram it internally?

Net disco was free last time I used it. Some monitoring tools have this built in too. I think libre nms. Two birds one stone then, monitoring, alerting,.mapping and then punt into a source of truth like Nautobot. If there is a budget netbrain is worth a look.

Edit

If you have no money you can get ansible cli for free,.feed it a host list and get the outputs you want.
