# WHATPORT(10616)

## NAME

port 10616 — Unassigned — Unregistered with IANA and not the default for any well-known software.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA lists no service for 10616, and Nmap's database calls it unknown, open on about 0.04% of scanned hosts. There is no protocol the number implies. Anything answering is application-specific, so identify it from the process or the banner rather than from a port list.

## EXPOSURE

**Expose with care.** No registration means no assumptions about what the service does or whether it authenticates. Identify it before exposing it.

## CHECK

```sh
sudo lsof -nP -iTCP:10616 -sTCP:LISTEN
```
