Perhaps this is a weird question I have, but I’ve been watching some technotim videos lately and he seems to have local dns addresses for local services. Perhaps I’ve got this wrong, but if not: how would you go over doing this?
I have a pterodactyl dashboard, which I access locally using the machines IP and the port, but it would be great to have a pterodactyl.example.com domain, which isn’t accessible from other networks, but does work on my own network. I also still want some services exposed to the internet, so I’m not sure if this would work.
But the attacker should know the internal and the external DNS. If the internal DNS doesn’t have any SSL certificate on its name, it’s impossible to discover.
By the way, I always suggest to reach services through VPN and use something like Cloudflare tunnel for services that must be public.
P.s. Shouldn’t public and private DNS be inverted in your curl example?
