Port 2652: InterPathPanel — A Name Without a Story

What Is Port 2652?

Port 2652 sits in the registered ports range (1024–49151) — the middle tier of the port numbering system, between the well-known ports (0–1023) that anchor the core Internet protocols and the dynamic/ephemeral ports (49152–65535) that operating systems hand out temporarily for outgoing connections.

Registered ports are assigned by IANA (the Internet Assigned Numbers Authority). You can request one. You fill out the paperwork, name your service, provide a contact, and IANA records the assignment. The port is yours.

Port 2652 is registered. The name in the IANA registry is InterPathPanel, assigned to a contact named Stephen Misel.¹

And that is essentially all that exists.

The Ghost Registration

InterPathPanel left no public record. No documentation. No open-source repository. No product page. No forum posts. No security advisories mentioning it. A Perl developer named Stephen Misel appears on CPAN, but no connection to InterPathPanel software surfaces anywhere.²

This happens more often than you might expect. The IANA registry contains hundreds of port assignments where the registrant filed a claim — perhaps for internal enterprise software, a product that never shipped, or a project abandoned long ago — and the port number became a permanent placeholder for something that no longer exists, or never did publicly.

The assignment is real. The software is a ghost.

In practice, port 2652 behaves as an unclaimed port. Nothing listens on it by default on any standard operating system or common server stack. If you see traffic on it, something put it there deliberately.

What the Registered Range Means

Registered ports occupy a specific position in the trust hierarchy:

• Well-known ports (0–1023) require root/administrator privileges to bind on most systems. These are reserved for foundational protocols: HTTP on 80, HTTPS on 443, SSH on 22.
• Registered ports (1024–49151) can be bound by any process without elevated privileges. IANA tracks assignments here, but enforcement is social, not technical — any software can use any port in this range.
• Dynamic/ephemeral ports (49152–65535) are used by operating systems for outbound connections. They're temporary and unassigned by design.

Port 2652's registered status means IANA has noted the claim, but nothing prevents another application from using it. The registration is a courtesy record, not a lock.

How to Check What's Listening

If you see activity on port 2652 and want to know what's using it:

On Linux/macOS:

# Show what process is listening on port 2652
sudo ss -tlnp | grep 2652

# Or with lsof
sudo lsof -i :2652

On Windows:

netstat -ano | findstr :2652

The output will show you the process ID (PID). From there, you can identify the application using Task Manager, ps, or Get-Process in PowerShell.

If nothing is listening, the port is idle — which is the expected state for port 2652 on any system that hasn't deliberately opened it.

Why Ghost Registrations Matter

The IANA registry is the closest thing the Internet has to a port phone book. When it contains a name, tools and documentation repeat that name. Port scanners flag it. Security guides mention it. The name "InterPathPanel" will propagate through port databases indefinitely, even though no one can tell you what InterPathPanel does or whether it still exists.

This is a small but honest example of how naming infrastructure outlives the things it was built to name. The port is available. The registration is a historical artifact. The Internet moves on regardless.
