# WHATPORT(7911)

## NAME

port 7911 — Unassigned — Unassigned at IANA, inside the empty 7904-7912 block — no standard service claims it.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA leaves 7904 through 7912 unassigned, so 7911 has no registered name; Nmap likewise records it as unknown, open on roughly 0.04% of scanned hosts. The next registration up is 7913 (qo-secure). Nothing common binds 7911 by default, so a listener is a local choice.

## EXPOSURE

**Expose with care.** No registration, no expectations — find the process behind it and rate that service rather than the number.

## CHECK

```sh
sudo lsof -nP -iTCP:7911 -sTCP:LISTEN
```
