Port 1060: POLESTAR — A registered ghost

Port 1060 sits in the registered ports range with an official assignment to a service called POLESTAR. If you've never heard of it, you're not alone.

What Is POLESTAR?

POLESTAR is registered with IANA as the official service for port 1060, available on both TCP and UDP.¹ The name appears in port registries and network tools like Wireshark, but details about what POLESTAR actually did—or does—are scarce.

This is common in the registered ports range. Someone built a service, registered a port number with IANA, and then the service faded from use. The port assignment remains, a placeholder in the registry that most networks will never encounter.

The Registered Ports Range

Port 1060 belongs to the registered ports range: 1024 through 49151.²

This range works differently than the well-known ports (0-1023):

• Anyone can register — You don't need special permission to request a port assignment from IANA
• No enforcement — Nothing prevents you from running a different service on port 1060
• Historical artifacts — Many assignments date back decades to services that no longer exist

Think of it as a phone book where half the numbers are disconnected, but the listings remain.

Why Does This Port Exist?

Port 1060's existence serves a purpose even if POLESTAR doesn't:

It reserves the space. If you're building a new network service, you won't accidentally pick 1060 and conflict with legitimate POLESTAR traffic (however unlikely that is).

It provides standardization. Network tools can display "polestar" when they see port 1060 in use, giving administrators a starting point for investigation.

It shows history. The registered ports range is an archaeological record of network services—what we built, what we tried, what survived, and what didn't.

Checking What's Actually Using Port 1060

The official assignment doesn't tell you what's actually running on your network. To check:

On Linux or macOS:

sudo lsof -i :1060

On Windows:

netstat -ano | findstr :1060

Using nmap:

nmap -p 1060 target-address

You might find nothing. You might find POLESTAR. You might find something completely different—a custom application that chose port 1060 because it was available and the developer never checked the registry.

The Reality of Registered Ports

Port 1060 represents a truth about the registered ports range: official assignments are more suggestion than law.

Unlike well-known ports where port 80 really does carry HTTP and port 443 really does carry HTTPS, registered ports are loosely held. The assignment exists. The service might not. Something else might be using the port instead.

This isn't chaos—it's pragmatism. With over 48,000 registered port numbers, strict enforcement would be impossible. The registry provides coordination for those who want it and a reference for those who need it, but it doesn't dictate reality.
