Port 2467: Unassigned — A Registered Port with No Claimed Service

What Port 2467 Is

Port 2467 has no assigned service. The Internet Assigned Numbers Authority (IANA), which maintains the official registry of port number assignments, lists this port as unassigned.¹

That means no protocol has formally claimed it. No RFC defines it. No standard body has documented what should run here.

The Registered Port Range

Port 2467 falls in the registered port range: 1024–49151.

This range exists between the well-known ports (0–1023), which are reserved for foundational Internet services like HTTP, HTTPS, and SSH, and the ephemeral ports (49152–65535), which operating systems assign temporarily for outgoing connections.

The registered range was designed for software vendors and developers to claim specific port numbers for their applications. A company building a database or a communication tool could register a port with IANA so their software wouldn't conflict with others. In practice:

• Registration requires an application to IANA but is not mandatory
• Many applications use registered-range ports without registering them
• Roughly 47,000 ports exist in this range; IANA has formally assigned far fewer
• Port 2467 is one of the unassigned majority

Known Unofficial Uses

No widely observed unofficial use for port 2467 has been documented in security databases, vulnerability reports, or network traffic analysis resources. It does not appear in common malware port lists or known exploit databases.

This is unremarkable. Most unassigned registered ports simply go unused, or appear quietly in private software deployments that never make it into public documentation.

How to Check What's Listening on This Port

If you see traffic on port 2467 and want to know what's using it:

On Linux or macOS:

sudo ss -tlnp | grep 2467
# or
sudo lsof -i :2467

On Windows:

netstat -ano | findstr :2467
# Then look up the PID:
tasklist | findstr <PID>

These commands show which process, if any, has bound to port 2467. If nothing appears, nothing is listening.

Why Unassigned Ports Matter

The port system works because most software agrees to use the same numbers for the same services. Port 80 is HTTP everywhere. Port 443 is HTTPS everywhere. That consensus is what makes the Internet function without prior coordination.

Unassigned ports represent the space outside that consensus. They can be used by anyone for anything — legitimate private applications, internal tools, custom protocols, or occasionally malware trying to avoid detection on better-known ports.

Seeing traffic on an unassigned port isn't inherently suspicious, but it is worth understanding. The question is always: what process put it there, and why?
