# WHATPORT(6379)

## NAME

port 6379 — Redis — Redis, registered with IANA and running with no password unless you set one.

Protocol: TCP  
IANA registry

## DESCRIPTION

Port 6379 is the registered Redis port and the default for every Redis and Redis-compatible server. Redis is designed for trusted networks: authentication is off unless you configure ACLs or requirepass. Since 3.2 it starts in protected mode, replying only to loopback when it binds all interfaces with no password set, but plenty of deployments disable that or bind explicitly and end up open.

## EXPOSURE

**Do not expose.** Redis's own docs say do not expose the port to the internet — one FLUSHALL wipes the dataset, and CONFIG-based file writes can lead to code execution.

## CHECK

```sh
redis-cli -h 127.0.0.1 -p 6379 PING
```
