Port 1415: DBStar — A ghost in the registry

Port 1415 sits in the registered ports range (1024-49151), officially assigned to a service called DBStar. Both TCP and UDP protocols are registered under this name to Jeffrey Millman.¹

The problem? DBStar has essentially vanished from the Internet. No active documentation. No official website. No user community. The registration exists, but the service appears to be a ghost.

What Is DBStar?

DBStar was registered as a database service. Beyond that, the historical record is silent. Some port databases incorrectly list FileMaker Pro as using port 1415,² but FileMaker's actual network ports are 5003 and 5353.³ The association appears to be an error that propagated through informal port listings.

What likely happened: someone developed DBStar, registered the port with IANA (the Internet Assigned Numbers Authority), and then the project died, pivoted, or remained so niche that it left no trace. The port number remains claimed.

The Registered Ports Range

Port 1415 belongs to the registered ports range—numbers that require IANA registration but aren't as strictly controlled as well-known ports (0-1023). This range exists for:

• Commercial applications
• Proprietary protocols
• Services that need a consistent port number but aren't universal Internet infrastructure

To register a port in this range, you submit an application to IANA. If approved, the number is yours. But there's no requirement that your service actually succeed, or even ship. The registry is full of ports like 1415—claimed by projects that never reached critical mass.

Why Unassigned and Dormant Ports Matter

The port number space is finite. 65,535 ports per protocol. Many are claimed but unused. This creates an interesting problem: should IANA reclaim ports that appear abandoned? Should there be a "use it or lose it" policy?

Currently, there isn't. Once registered, a port typically stays registered. This means the namespace slowly fills with ghosts—numbers that point to services that no longer exist or never really did.

Port 1415 is one of those ghosts. A tombstone in the registry. Someone had a plan. They registered the port. And then something else happened.

Checking What's on Port 1415

If you want to see what's actually listening on port 1415 on your system:

Linux/macOS:

sudo lsof -i :1415
# or
sudo netstat -tuln | grep 1415

Windows:

netstat -ano | findstr :1415

You'll almost certainly find nothing. Because DBStar, whatever it was, isn't running on your machine. And probably isn't running anywhere anymore.

The Reality of Port Numbers

Most port numbers are like this. The famous ones—22 for SSH, 443 for HTTPS, 25 for email—get all the attention. But they're the exception. The vast majority of registered ports are claimed by services you've never heard of, running protocols that never reached adoption, serving purposes that made sense to someone once and then didn't.

Port 1415 is the Internet's nervous system being honest about itself. Not every connection succeeds. Not every protocol survives. Not every port number fulfills its purpose.

But the number remains, claimed and waiting, just in case DBStar ever comes back.
