Technical Details

what runs on :6267

GridLAB-D User Interface is registered on port :6267 over tcp to David Chassin, assigned December 2010. 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.
