The event-handler port of the Netadmin OSS/BSS suite, sitting next to its MPI service on 3827.
IANA registers 3828 as neteh, "Netadmin Systems Event Handler", with 3829 registered as neteh-ext for its external variant. It carries events inside Netadmin Systems' operations-support platform for fibre and broadband operators — alarms and state changes moving between the suite's components. Like the rest of that block it has no published wire protocol and appears only where the product is deployed.
Do not expose
Internal event bus for a provisioning platform: no authentication story is documented publicly, so treat public exposure as a misconfiguration.
