Technical Details

what runs on :2396

Wusage is registered on port :2396 over tcp and udp to Thomas Boutell. We don't have a technical write-up for it beyond the IANA registry entry.

In nmap's internet-wide scan data this port is never observed open, so if it's open on your network it's more likely a custom or misconfigured service than the registered one.
