What Port Range Is This?
Port 60804 lives in the dynamic/ephemeral port range: 49152-65535.1 These ports are intentionally unassigned by IANA. They exist for a specific reason: to give applications a place to allocate temporary ports without asking permission or registering anything.
What This Range Means
The ephemeral port range serves a fundamental networking need. When your browser opens multiple connections to different websites simultaneously, it doesn't get port 443 for the second connection—port 443 belongs to HTTPS. Instead, the operating system allocates an ephemeral port from this range for the client side of each connection.1
This range also handles private application communication. When a server needs to open a side channel to a client (like RPC applications or some file transfer protocols), it reaches into this range and grabs a temporary port for that conversation.1
No Official Use, By Design
Port 60804 specifically has no assigned service, and search results show no widespread unofficial use either.2 This is not a problem—it's the entire point. The ephemeral range exists so that thousands of applications, across millions of computers, can simultaneously allocate ports without collision or coordination.
If you see port 60804 listening on your system, it's being used by some application for temporary communication. You won't find a standard service definition for it because applications in this range are supposed to define their own behavior.
How to Check What's Using This Port
If you want to identify what's listening on port 60804:
Linux/macOS:
Windows:
These commands show which process has claimed the port. The port number itself won't tell you what service it is—only the process name will.
Why Unassigned Ports Matter
The Internet's port system works because it has three tiers: well-known ports (0-1023) that are officially assigned and stable across all systems, registered ports (1024-49151) that applications can reserve with IANA, and these dynamic ports (49152-65535) that are free for the taking.
Port 60804 is part of the infrastructure that allows the Internet to scale. Every time your computer opens a connection, every time an application needs a temporary channel, it's probably using a port in this range. The system works because no one owns these ports—everyone does, temporarily.
