# WHATPORT(8008)

## NAME

port 8008 — HTTP alternate; Google Cast device HTTP — A registered HTTP alternate port, and the plaintext HTTP interface of every Chromecast.

Protocol: TCP  
IANA: http-alt

## DESCRIPTION

IANA registers 8008 as http-alt, the same designation 8080 carries, so it is a legitimate second home for web servers — IBM HTTP Server and many appliances use it. On a home network the far more likely answer is a Google Cast device: pychromecast's DIAL client builds its device URLs as `http://<ip>:8008`, and that endpoint returns the device's `eureka_info` — name, model, firmware, Wi-Fi details — alongside the TLS control channel on 8009. Nmap sees 8008 open on roughly 0.7% of scanned hosts, making it one of the busier alternate HTTP ports.

## EXPOSURE

**Expose with care.** As a web port it is as safe as the app behind it. As a Cast device it is not: the 8008 interface answers device-information and setup requests without authentication, so it must stay on the LAN.

## CHECK

```sh
curl -s http://TARGET:8008/setup/eureka_info
```
