What Port 60718 Is
Port 60718 exists in the dynamic and/or private port range (49152–65535), the Internet's commons. 1 It is not officially assigned by IANA. No registry entry exists. No RFC defines it. It is unowned.
What This Range Means
The Internet's port architecture has three tiers:
Well-known ports (0–1023): These are officially assigned. SSH is 22. HTTP is 80. HTTPS is 443. The Internet Foundation Consortium (IANA) guards these like property deeds. You cannot claim port 443 for your custom service. It belongs to HTTPS, globally, permanently.
Registered ports (1024–49151): Companies and organizations can register these. If you're building a protocol you want to be widely recognized, you can request a port in this range and it becomes part of the official record. It says: "This is official. People know what to expect."
Dynamic/private ports (49152–65535): These are the exception. IANA doesn't assign them. They're reserved for exactly what port 60718 is: temporary use, private applications, ephemeral connections. An application needs a port? It grabs one from this range and uses it until it shuts down. The next process may use the same port tomorrow.
Port 60718 is in that third category. It is provisional. It is temporary. It is, by design, unimportant.
Known Uses
Search results occasionally mention Apple Xsan in connection with ports in this range. Xsan is Apple's storage area network system—it uses ports from the dynamic range for filesystem access operations. 2 Port 60718 specifically is not officially registered to Xsan, but if you're seeing it in use on a Mac system, it's likely Xsan claiming it for a temporary connection to shared storage.
Beyond that, port 60718 has no documented purpose. It may be claimed by any application on any system, used for any protocol, and abandoned when the application closes.
How to Check What's Listening
If you want to see what, if anything, is using port 60718 on your system:
On Linux/macOS:
On Windows:
The output will tell you the process ID (PID) and application name using the port. From there, you can identify what's claiming this temporary space.
Why Unassigned Ports Matter
The existence of the dynamic port range is what makes the Internet flexible. SSH didn't have to wait for a committee. HTTP didn't need a registry vote. They claimed well-known ports, yes—but only because they became fundamental.
Most services don't become fundamental. Most applications need a port for one connection, one session, one temporary moment. They cannot crowd into the well-known range. They would collide. The Internet would break.
So we created the ephemeral range. The dynamic ports. The unassigned commons. Any application can claim any port from 49152 to 65535, use it, and release it. Thousands of processes may have used port 60718 across the Internet in the time you've been reading this.
Port 60718 is proof that the Internet thrives not because everything is carefully controlled, but because most of it is deliberately left uncontrolled.
