Bloomberg's second registration in this block, for the "intelligent client"; undocumented publicly.
IANA lists blp4 on TCP and UDP 8294, "Bloomberg intelligent client", registered by Bloomberg in May 2006 alongside blp3 on 8292. As with the rest of the Bloomberg port registrations, the protocol is proprietary and unpublished, and terminal deployments show up as outbound connections from workstations rather than as services you can probe. Nmap's data puts it open on roughly 0.015% of hosts on TCP.
Expose with care
The registration describes client software, not a server you would publish. Treat a listener here as unidentified until you name the process.
