When normal people ask for your address, they want your house number and street name. But ask a developer, and you'll unlock their final form of networking nerdery.
First, they hit you with a private IP address (173.168.16.11) like they're giving out nuclear launch codes. When pushed for a "local" address, they retreat to the ultimate programmer safe space - localhost (127.0.0.1) - because home is where your server runs.
And when specifically asked for a physical address? They go full galaxy-brain with a MAC address (28:05:FF:58:31:05). It's like asking someone where they live and they respond with their DNA sequence.
Developers: making simple questions complicated since the invention of the network stack.
