# WHATPORT(8086)

## NAME

port 8086 — InfluxDB HTTP API — InfluxDB's HTTP API and UI — the default for every InfluxDB version.

Protocol: TCP  
IANA: d-s-n

## DESCRIPTION

InfluxDB's http-bind-address defaults to :8086, which serves both the write/query API and, since 2.x, the browser UI. Because the default binds all interfaces rather than loopback, a stock install on a cloud VM is reachable from anywhere the firewall allows. IANA has 8086 registered to d-s-n, a SCADA rendezvous port, which you will essentially never meet; a listener on 8086 is a time-series database. Telegraf agents, Grafana data sources and Kubernetes monitoring stacks are the usual clients.

## EXPOSURE

**Do not expose.** It is a database API speaking plain HTTP by default, with API tokens sent in the clear; keep it on a private network or behind a TLS-terminating proxy.

## CHECK

```sh
curl -s --max-time 5 http://TARGET:8086/health
```
