Port 298 is officially unassigned. It has no registered service, no RFC defining its purpose, no protocol waiting behind it. It exists as empty space in the well-known port range—a number reserved for future use that the future hasn't needed yet.
What Range Port 298 Belongs To
Port 298 falls within the well-known ports range (0-1023), also called system ports. This is the most privileged section of the port number space. These ports typically require root or administrator privileges to bind to, and they're reserved for core Internet services assigned through formal IETF or IESG approval processes.1
The well-known range includes essential services like HTTP (80), HTTPS (443), SSH (22), and DNS (53). Port 298 sits among them, reserved but unused.
According to IANA records, port 298 falls within the unassigned block spanning ports 288-307—a stretch of 20 consecutive ports that remain unclaimed.2
What This Means
Being unassigned doesn't mean port 298 is broken or unusable. It means:
- No official service is registered here - IANA has not assigned any protocol or service to this port number
- It's available for future assignment - If someone develops a protocol that needs a well-known port, 298 could be assigned through the proper IANA procedures
- It requires formal approval to use - You can't just decide to use port 298 for your application. Well-known ports require IETF Review or IESG Approval to be officially assigned1
- Nothing should be listening here by default - On a properly configured system, no standard service will be bound to port 298
Why Unassigned Ports Matter
The Internet's port system isn't infinite. There are only 1,024 well-known ports, and once they're assigned, changing them breaks backward compatibility across millions of systems. IANA guards these numbers carefully.
Unassigned ports like 298 represent breathing room—space for protocols we haven't invented yet, services we don't know we'll need. They're the margin for future expansion.
The existence of unassigned ports also reveals something about the Internet's evolution. We've been using TCP/IP since the early 1980s, and we still haven't needed all 1,024 well-known ports. The designers built in more capacity than four decades of Internet growth has required.
Checking What's Listening on Port 298
Even though port 298 is officially unassigned, it's possible (though unusual) for something to be listening here on your system—either a misconfigured service, custom software, or something unauthorized.
On Linux or macOS:
On Windows:
If you find something listening on port 298 that you didn't explicitly configure, investigate it. Unassigned ports are sometimes used by malware precisely because they're unexpected.
The Empty Spaces
There are hundreds of unassigned ports scattered throughout the well-known range. Port 298 is one of many gaps in the registry—reserved numbers waiting for purposes that may never arrive.
Some unassigned ports will eventually find their calling. Others will remain empty indefinitely, artifacts of a numbering system that allocated more space than was strictly necessary.
Port 298 has been waiting since the IANA registry was formalized. It sits between port 296 (unassigned) and port 300 (unassigned), in a quiet neighborhood where nothing happens.
Maybe someday a new protocol will claim it. Maybe it will wait forever.
Either way, it's here—an address without a destination, a number without a purpose, a door that leads nowhere.
