What Port 462 Is (Officially)
Port 462 is registered with IANA for DataRampSrvSec (DataRamp Secure Service) on TCP.1 It sits in the well-known port range (0-1023), which is reserved for system services and protocols assigned by the Internet Assigned Numbers Authority.
Well-known ports are supposed to be the Internet's permanent addresses—the ports you can count on. Port 80 for HTTP. Port 443 for HTTPS. Port 22 for SSH. These are the ports that built the Internet.
Port 462 is not one of them.
What DataRampSrvSec Was (Unknown)
Nobody knows. The IANA registry lists "DataRampSrvSec" as the service name, but there's no RFC defining it, no protocol specification, no software that uses it. Modern companies use the "DataRamp" name for data management services, but they have no connection to this port assignment.2
This suggests one of three possibilities:
- It was registered but never deployed — Someone reserved the port for a service they planned to build but never launched
- It was deployed and abandoned — The service existed briefly, then disappeared without leaving documentation
- It's still used somewhere obscure — A niche application runs on port 462 in networks we can't see
The well-known port range was created in an era when you could email Jon Postel and get a port number assigned for your experimental protocol. Not every experiment succeeded. Not every assignment became infrastructure.
Port 462 is a reminder that the well-known port range contains not just the Internet's greatest hits, but also its abandoned drafts.
What This Port Range Means
Ports 0-1023 require root/administrator privileges to bind on Unix-like systems. This restriction exists because these ports were meant for system services—things you could trust because only the system administrator could run them.
Getting a well-known port assignment was once prestigious. It meant your protocol mattered enough to be part of the Internet's permanent infrastructure. Port 462 has that assignment. But without documentation, without implementations, without community memory, the assignment is just bureaucracy.
How to Check What's Listening
Even though port 462 has no known official use, something could still be listening on it—either a legacy application, unofficial software, or something malicious.
On Linux/Mac:
On Windows:
If you find something listening on port 462, investigate what it is. Unused ports are sometimes exploited precisely because nobody's watching them.
Why Unassigned Ports Matter
Not every registered port becomes infrastructure. The well-known port range contains hundreds of assignments like DataRampSrvSec—services that were registered but never widely deployed, protocols that were defined but never implemented, good ideas that never found their moment.
These ghost ports serve a purpose: they show us that the Internet wasn't inevitable. For every SSH and HTTPS, there were dozens of protocols that didn't make it. Port 462 is one of them.
The Internet we have is not the only Internet we could have built.
The Honest Truth
Port 462 is assigned but unused. If you need a well-known port for a new service, you probably shouldn't use this one—it's officially taken. But if you're looking for what runs on port 462, the answer is: nothing you've heard of, and probably nothing at all.
Some ports carry the weight of the Internet. Port 462 carries only its registration—a name without a protocol, a number without a purpose, a reservation for a service that never arrived.
