What This Port Range Means
Port 60072 falls within the dynamic and private port range (49152–65535), which IANA explicitly does not assign or control.1 This range exists for a specific reason: temporary connections. When an application needs to send data, it doesn't always claim a permanent port. Instead, the operating system assigns it an ephemeral port from this range, uses it for the communication, and releases it when finished. 2
No application permanently owns port 60072. No service is registered there. It's available for any process that needs a temporary endpoint.
Known Unofficial Uses
Windows DNS servers have been documented using ports in the range 60023–60081 (which includes 60072) for DNS query randomization.3 This is a security practice: by randomizing which port DNS queries originate from, the server makes it harder for attackers to predict and intercept DNS traffic. The port is borrowed briefly, used once or a few times, then released.
This is exactly what the dynamic range is designed for.
How to Check What's Listening
If you suspect port 60072 is in use on your system right now, you can check with these commands:
On Linux/macOS:
On Windows:
These commands show what process is using the port at that moment. The answer changes constantly—that's the nature of ephemeral ports.
Why This Matters
The dynamic range protects the Internet's structure. There are only 65,535 port numbers total. The well-known range (0–1023) holds the permanent institutions: HTTP, HTTPS, SSH, DNS, SMTP. The registered range (1024–49151) holds named services. The dynamic range (49152–65535) is the commons—unassigned, always available, always temporary.
Port 60072 is part of that commons. It will probably never matter to you directly. But somewhere right now, an operating system is assigning it to a connection, using it for a moment, and releasing it. The whole thing takes milliseconds. That's the port working exactly as intended.
