Registered to Bloomberg for the Bloomberg Professional service; no public protocol documentation.
IANA assigns the service name blp3 on TCP and UDP 8292 to Bloomberg, described only as "Bloomberg professional", registered in May 2006. Bloomberg's terminal software is a proprietary client that reaches out to Bloomberg's network, so this normally appears as an outbound flow on a trading-floor workstation rather than as a listener you can scan. The wire protocol is not published. Nmap sees the port open on roughly 0.02% of hosts, which is registry noise more than deployment.
Expose with care
If something is actually listening here it is not the Bloomberg client, which is an outbound connector. Identify the process before deciding anything about exposure.
