What This Port Is
Port 1346 is officially registered with IANA for Alta Analytics License Manager (alta-ana-lm).1 This was license management software from Alta Analytics, a company that appears to have ceased operations years ago.
The port sits in the registered range (1024-49151), meaning someone formally requested it from IANA, provided documentation, and got official approval. Then the company folded. The software disappeared. The port remains.
The Reality
You will almost never see traffic on port 1346.
Alta Analytics is gone. Their website is defunct. The software is legacy-ware that nobody runs anymore.2 If you find something listening on this port, it's either:
- An ancient installation that someone forgot about
- Software that chose this port because it was "available" without checking the registry
- Something pretending to be something else
Why Unassigned-in-Practice Ports Matter
The IANA registry contains thousands of ports like 1346—officially registered, practically abandoned. They were claimed during the early Internet boom when companies requested ports optimistically, expecting their software to become infrastructure.
Most didn't.
These ports serve a purpose: they remind us that registration isn't the same as use. Just because a port has a name in the registry doesn't mean anyone's listening. Just because a door exists doesn't mean it's open.
What Range This Belongs To
Port 1346 sits in the registered ports range (1024-49151). These ports are:
- Assigned by IANA to specific services through a formal process
- Not privileged (any user can listen on them, no root required)
- Supposed to be used only for their registered purpose
- Frequently ignored by developers who just pick a number
The range below (0-1023) requires root privileges. The range above (49152-65535) is for temporary connections. This middle ground is where companies staked their claims.
How to Check What's Listening
On Linux or macOS:
On Windows:
If you find something listening on port 1346 and it's not ancient license management software, investigate. Abandoned ports sometimes get repurposed by malware precisely because nobody expects traffic there.
The Lesson
Not every registered port matters. Not every door gets used. The Internet is full of these abandoned addresses—officially claimed, practically empty, waiting for traffic that will never come.
Port 1346 is a ghost town. A reminder that registration lasts longer than the companies that requested it.
