Is port 2846 dangerous?

We have no specific security note for port 2846. Its risk depends on the program actually listening on it. General advice for other services services:

  • Close the port if nothing on the host needs it.
  • Identify the process that listens on it (commands below) before opening it in a firewall.
  • Expose a service only to the networks that use it.

03 Check it

Which program uses port 2846, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2846'      # process listening on 2846
sudo lsof -nP -i :2846

macOS

sudo lsof -nP -i :2846

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2846 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2846
netstat -ano | findstr :2846

From another machine

nmap -p 2846 -sV <host>
sudo nmap -sU -p 2846 <host>
nc -zv <host> 2846

Block it in the firewall

sudo ufw deny 2846/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2846" -Direction Inbound -LocalPort 2846 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2846 used for?

Port 2846 is assigned by IANA to aimpp-hello (AIMPP Hello).

Is port 2846 TCP or UDP?

Port 2846 is registered for TCP and UDP.

Is it safe to open port 2846?

It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Close the port if nothing on the host needs it.

How do I check if port 2846 is open?

On Linux run "ss -ltnup 'sport = :2846'", on macOS "lsof -nP -i :2846", and on Windows "netstat -ano | findstr :2846" to see the local process. From another machine, "nmap -p 2846 <host>" shows whether it is reachable.
