# WHATPORT(8292)

## NAME

port 8292 — blp3 — Bloomberg professional — Registered to Bloomberg for the Bloomberg Professional service; no public protocol documentation.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

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.

## EXPOSURE

**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.

## CHECK

```sh
sudo lsof -nP -iTCP:8292 -sTCP:LISTEN
```
