# WHATPORT(33899)

## NAME

port 33899 — Unassigned — Unregistered and unnamed in scanner databases; open on well under a tenth of a percent of hosts.

Protocol: TCP  
IANA registry

## DESCRIPTION

33899 has no IANA assignment and no service name in Nmap's database, which records it open on about 0.04% of scanned hosts. Like everything between 32768 and 60999 it doubles as a Linux ephemeral port, so an open socket here is as likely to be an outbound connection as a service. Identify it by the process, not by the number.

## EXPOSURE

**Expose with care.** Nothing about the port number tells you whether it is safe; run a version scan or check the owning process before allowing it through a firewall.

## CHECK

```sh
nc -vz -w 3 TARGET 33899
```
