Port 1054 is officially registered with IANA for BRVREAD, a network service used by Brother printers and multifunction devices.12
What BRVREAD Does
BRVREAD is part of Brother's network printing infrastructure. When you send a print job to a Brother networked printer, various ports handle different aspects of the communication. Port 1054 is one of them.
The specifics of what BRVREAD reads or communicates aren't publicly documented in detail—it's vendor-specific infrastructure. Brother maintains it, Brother devices use it, and it works quietly in the background.
The Registered Port Range
Port 1054 sits in the registered port range (1024-49151). These ports are registered with IANA for specific services but don't have the same universal recognition as well-known ports (0-1023).
Registered ports serve:
- Vendor-specific applications (like BRVREAD for Brother)
- Specialized protocols that aren't universally deployed
- Services that need a consistent port number but aren't foundational Internet infrastructure
Anyone can request a registered port from IANA for their application or service. Brother did this for BRVREAD.3
When You'll See This Port
If you have Brother networked printers or multifunction devices on your network, port 1054 may be active. You won't see it in everyday use—it's background infrastructure.
If your firewall logs show traffic on port 1054, and you have Brother devices, that's likely what's happening. Brother's own documentation lists various ports needed for network communication with their machines.4
Checking What's Listening
On Linux or macOS:
On Windows:
If something's listening and you don't have Brother devices, that's worth investigating.
Why Vendor Ports Matter
Ports like 1054 show how the Internet's port system accommodates the real world. Not everything is HTTP and SSH. Printers need to communicate. Security cameras need ports. Industrial sensors need ports. HVAC systems need ports.
The registered port range exists for exactly this: services that are real, necessary, and specific, but not universal.
BRVREAD isn't famous. It doesn't appear in security tutorials or networking textbooks. But on networks with Brother printers, it's there, doing its work, part of the vast mesh of protocols that make networked devices actually work.
Security Considerations
Port 1054 should only be accessible on your local network. There's no reason for BRVREAD traffic to cross the Internet.
If you're not using Brother devices, nothing should be listening on port 1054. If something is, investigate.
Like most vendor-specific protocols, BRVREAD wasn't designed with Internet exposure in mind. Keep it behind your firewall. Let it talk to printers on your LAN. Don't let it talk to the world.
