What This Port Is
Port 2782 sits in the registered ports range — the band from 1024 to 49151 where software developers and organizations can formally claim a port number through IANA, the Internet Assigned Numbers Authority.
Unlike well-known ports (0–1023), which carry protocols the entire Internet depends on, registered ports are reservations. You apply, IANA records your name and contact information, and the port is yours. Whether you ever ship anything to it is another matter.
Port 2782 has a name in IANA's registry: everydayrc, on both TCP and UDP. The assignee is Ahti Heinla, registered June 2002.1
Who Registered It
Ahti Heinla is an Estonian software engineer with a brief but consequential biography. In 1999, he helped build Everyday.com — a digital newspaper commissioned by Tele2, developed alongside Jaan Tallinn and Priit Kasesalu. By 2000, the same team had co-created Kazaa, the peer-to-peer file sharing network that filled the vacuum left when Napster shut down. By 2003, they were helping ship Skype.2
Port 2782 was registered in June 2002 — the year between Kazaa and Skype. The name "everydayrc" almost certainly points back to Everyday.com, with "rc" suggesting some kind of remote control or communication layer built for that platform. It was never publicly documented, never shipped as a known service, and never became part of anything observable.
What Heinla was building in those months, nobody really knows. Port 2782 is the only trace.
What Runs on It Now
Almost certainly nothing related to everydayrc. The service never had a public life.
In practice, port 2782 may show up on machines running software that picks ports dynamically from the registered range — database connections, development servers, internal APIs. If you're seeing traffic here, it's almost certainly not everydayrc.

Why Unassigned (and Abandoned) Ports Matter
The registered port range has 48,128 slots. Not all of them are active. Some were claimed and abandoned. Some were claimed for internal projects that never shipped. Some were claimed by people who went on to do much larger things.
The registry keeps these entries indefinitely. IANA doesn't reclaim ports the way domain registrars reclaim expired domains. Once registered, a port number stays associated with its assignee in the records even if the service it was meant for has been quietly forgotten for twenty years.
Port 2782 is one of those. The man who registered it changed the way the world communicates. This port was not part of that story — but it was there while the story was being written.
