Status: Unassigned
Range: Well-known ports (0-1023)
Protocols: TCP and UDP available
What This Port Is
Port 795 has no official assignment. It exists—every port number from 0 to 65,535 exists—but nobody has claimed it. No protocol runs here. No RFC defines its purpose. The Internet Assigned Numbers Authority (IANA) maintains the registry of port assignments, and in that registry, port 795 is marked as unassigned.1
This doesn't mean the port is broken or missing. It means the port is available. Someone could request it. A new protocol could claim it. But right now, it's empty.
The Well-Known Range
Port 795 sits in the well-known ports range (0-1023), also called system ports. This range was originally reserved for services fundamental to Internet operation—HTTP on 80, HTTPS on 443, SSH on 22, DNS on 53. Services that everyone needs.
But not every port in this range has a service. Some were assigned decades ago and never used. Some were reserved for protocols that never materialized. Some, like 795, were simply never claimed.
The well-known range is managed by IANA through a formal process defined in RFC 6335.2 Getting a port assignment in this range requires IETF Review—a rigorous process where protocol designers present their case, explain why they need this specific port, and convince the Internet Engineering Task Force that the assignment serves the broader good.
Port 795 has never been through that process.
Why Unassigned Ports Matter
The existence of unassigned ports isn't a gap in the system—it's a feature. The Internet was designed to grow. New protocols emerge. New services appear. Having thousands of unassigned ports means there's room for what comes next.
Some unassigned ports see unofficial use. A company might run proprietary software on an unassigned port. A malware author might choose an empty port hoping to avoid detection. A developer testing a new protocol might grab the first available number.
None of this makes the port "assigned." Official assignment only happens through IANA. Everything else is just traffic passing through an address that technically belongs to nobody.
Checking What's Listening
If you need to see whether anything is listening on port 795 on your system:
Linux/macOS:
Windows:
If something appears, it's not because port 795 has an official service. It's because some program on your machine decided to use this port. That could be legitimate software, a testing environment, or something worth investigating.
Any unexpected listener on an unassigned port deserves scrutiny. Official services have official ports. When something uses a port with no official purpose, the question is: why?
The Adjacent Note
The range 788-799 is listed as unassigned in the IANA registry, but there's a note: "Unauthorized Use Known on port 796."1 This means someone, somewhere, decided to use port 796 for something unofficial, and it happened often enough that the Internet community noticed.
Port 795 has no such note. It's quieter than its neighbor. Not hijacked, not squatted, not even unofficially claimed. Just empty.
What Happens Next
Port 795 might stay unassigned forever. The Internet has 65,535 ports. Most protocols don't need their own dedicated well-known port anymore. Modern services use HTTP/HTTPS and negotiate everything else through higher-level protocols. The days of claiming a low-numbered port for every new service are largely over.
Or someone might request it tomorrow. A new protocol might emerge that needs a well-known port, and 795 might be chosen. The IANA process exists precisely for this—to allocate these empty addresses when they're genuinely needed.
For now, port 795 waits. A number without a name. An address without a service. A door that exists but leads nowhere.
