Also, "Subdomain in localhost", you might not be aware that "localhost" usually maps to 127.0.0.1, but actually anything under 127/8 is part of that network, so you can have 63000 open ports under 127.12.34.56 if you want, and they'll be separate from 127.0.0.1

I know that localhost maps to the 127.0.0.1 network, but I didn't know that we can map to all these different IPs. Thanks TIL.
