Finally, we arrive at 11501 . This is the port number. If an IP address is a building, a port is a specific window or door into that building. Computers do not simply receive data as a single, indistinguishable glob; they use ports to organize incoming and outgoing traffic. There are certain ports that are universally recognized—Port 80 for standard web traffic, Port 443 for secure encrypted traffic, Port 25 for email. These are the grand public thoroughfares of the digital city, heavily guarded, standardized, and bustling with activity.

Some routers or firewall rules may forward external traffic to your local machine. If you have explicitly forwarded port 11501 from your router to your computer, then localhost:11501 becomes accessible from the internet. localhost-11501
