Port 1144 sits in the registered ports range (1024-49151), officially unassigned by IANA. But in practice, it has become the standard port for AeroScout location-based services communicating with wireless access points.
What the Registered Ports Range Means
The Internet's 65,535 ports are divided into three ranges:
- Well-known ports (0-1023): Assigned by IANA for standardized services like HTTP (80) and SSH (22)
- Registered ports (1024-49151): Available for registration with IANA, but enforcement is light
- Dynamic/ephemeral ports (49152-65535): Free-for-all range for temporary connections
Port 1144 lives in the middle range. Anyone can request official assignment from IANA, but many services just start using a port without asking. That's what happened here.
The Unofficial Tenant: AeroScout Location Services
Port 1144 (UDP) is used by AeroScout MobileView and the AeroScout Engine for wireless location-based services. Access points from multiple vendors—Fortinet FortiAPs, Extreme Networks devices, and others—listen on UDP port 1144 for location data from AeroScout servers.12
The communication pattern is straightforward: the AeroScout Engine sends location updates to wireless access points over UDP port 1144. The access points receive these messages and use them to track the physical location of devices on the network.3
This is location tracking for enterprise environments—hospitals tracking medical equipment, warehouses tracking inventory, factories tracking tools. The access points become sensors in a positioning system, and port 1144 is how they receive their instructions.
Why This Port Matters
Unassigned ports are how the Internet grows organically. When a company needs a port for a new protocol, they can either:
- Request official assignment from IANA (takes time, requires documentation)
- Pick an unassigned port and start using it (fast, works if no one else picks the same port)
AeroScout chose option two. And because their deployment guides and documentation all specified port 1144, it became the standard across the industry. Competing vendors implemented support for it. Network administrators configured firewalls to allow it. The port became "assigned" through use rather than bureaucracy.
This is the gap between the official Internet and the actual Internet. The IANA registry says port 1144 is unassigned. But ask any network engineer who manages wireless location services, and they'll tell you: port 1144 belongs to AeroScout.
Security Considerations
Because port 1144 has no official assignment, security scanners won't flag it automatically. If you see UDP traffic on port 1144, you need to know what you're looking for.
For AeroScout deployments, this traffic is expected and necessary. For networks without location-based services, UDP 1144 traffic might indicate unauthorized software or reconnaissance activity.
The SANS Internet Storm Center tracks attack activity on various ports, including 1144.4 While it's not a common attack vector, any unassigned port can be exploited if left open unnecessarily.
How to Check What's Listening on Port 1144
On Linux or macOS:
On Windows:
These commands show which processes (if any) are using port 1144 on your system. For AeroScout deployments, you'll see the access point management software. For other systems, you should see nothing—unless something unauthorized has moved in.
