Port 10479 — Unassigned

Port 10479 has no official IANA assignment and no documented unofficial uses. It sits in the registered port range (1024–49151) ¹, which means it could be assigned at any time—but currently, it isn't.

The Port Ranges Explained

The Internet's 65,535 available ports are divided into three ranges: ²

• System Ports (0–1023): Reserved for system services and well-known protocols. SSH uses 22. HTTP uses 80. These ports require elevated privileges to use.
• Registered Ports (1024–49151): Where port 10479 lives. These can be registered with IANA for specific services, but registration is optional. Many are assigned to proprietary applications. Many remain empty.
• Dynamic/Private Ports (49152–65535): Temporary ports assigned on-the-fly. Your browser gets one of these when it connects to a web server.

Port 10479 lives in the middle band—the liminal space where protocols can be claimed but currently aren't.

What's Actually Running on Port 10479?

Probably nothing on your machine. But to check:

On Linux/macOS:

# Check if anything is listening on port 10479
sudo netstat -plnt | grep 10479

# Or use lsof (list open files)
sudo lsof -i :10479

# Or use ss (socket statistics, modern replacement for netstat)
sudo ss -plnt | grep 10479

On Windows:

netstat -ano | findstr 10479

If you see output, something is using it. If you see nothing, the port is truly empty.

Why Unassigned Ports Matter

Unassigned ports are the spare capacity of the Internet. They're:

• Available for new protocols: When someone invents a new service and needs a fixed port, they apply to IANA. Port 10479 could be next.
• Used for private applications: Companies and developers often claim unassigned ports internally for custom services that never leave their networks.
• Evidence of growth: That roughly 16,000 ports remain unassigned across the registered range shows the Internet still has room to expand without running out of address space.

Port 10479 isn't famous. It isn't carrying email or running web servers or securing SSH connections. It's just waiting. That's its honest role.
