Port 1077 sits in the IANA registry with a single word next to it: "IMGames." No description. No RFC. No documentation trail that explains what this service was supposed to do or whether anyone ever used it.
This is the story of a claimed port with no story.
What Lives on Port 1077
According to IANA's official registry, port 1077 is assigned to IMGames for both TCP and UDP.1 That's all we know with certainty.
The name suggests some kind of Internet gaming service—IM could stand for "Internet Multiplayer" or "Instant Messaging." The 1990s saw a wave of online gaming services like Mplayer, Heat.net, and the Microsoft Gaming Zone.2 IMGames might have been one of them.
Or it might have been something else entirely. The registry doesn't say. The Internet doesn't remember.
The Registered Ports Range
Port 1077 falls in the registered ports range (1024-49151). These ports are assigned by IANA to specific services, but unlike well-known ports (0-1023), they don't require special privileges to use.3
Anyone can apply to register a port. You fill out a form. IANA assigns you a number. Your service name goes in the registry alongside tens of thousands of others.
Many of these services never launched. Some launched and died quietly. Others are still running somewhere, but only a handful of people remember they exist.
What This Port Teaches Us
The port registry is an archaeological site. Most ports in the registered range are like port 1077—claimed by projects we can no longer reconstruct. The registry preserves the names but not the meaning.
This matters because:
Ports aren't just numbers. Each registered port represents someone who thought their service was important enough to claim a permanent address on the Internet. Most of those bets didn't pay off.
The registry never forgets. Port 1077 will be listed as "IMGames" forever, even though IMGames itself is gone. The Internet's phonebook outlives most of its residents.
Unassigned doesn't mean unused. Just because a port is officially registered doesn't mean anything is listening there. Just because a port is unassigned doesn't mean no one's using it. The registry describes intent, not reality.
Checking What's Actually Listening
If you want to know whether port 1077 is actually in use on your system, you can check:
On Linux or macOS:
On Windows:
Most likely, nothing is listening. Port 1077 is probably silent on your machine, just as it's silent across most of the Internet.
But somewhere, maybe, someone is still running IMGames. A server that never got the memo. A service that outlived its own documentation.
The Registry's Ghosts
The IANA port registry contains over 13,000 registered ports.1 Most of them are like port 1077—claimed but dormant, named but unexplained, registered but forgotten.
They're monuments to projects that didn't survive. To ambitions that couldn't be sustained. To the gap between claiming an address and building something people actually use.
Port 1077 is one of thousands of these ghosts. A door that someone claimed but may have never opened. A name in the registry that no one searches for anymore.
And yet it remains. Officially assigned. Permanently reserved. Waiting for traffic that may never come.
