While no single global standard assigns port 11501 to a specific service, several scenarios make this port appear frequently in development environments.
Many modern JavaScript frameworks (e.g., React, Vue, Angular) and build tools (Webpack, Vite) allow you to run a development server on a custom port. Developers often specify --port 11501 to avoid conflicts with other projects. For example: localhost-11501
npm start -- --port=11501
or
vite --port 11501
If you run a Linux app inside WSL2 that listens on port 11501, it will automatically be accessible from Windows’s localhost-11501 due to WSL2’s mirrored networking (depending on your WSL version and settings). If not, use localhost or find the WSL2 instance’s IP via wsl hostname -I. While no single global standard assigns port 11501
