# WHATPORT(8011)

## NAME

port 8011 — Unassigned — Unassigned by IANA — an overflow HTTP port and nothing more standardised than that.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA lists 8011-8014 as Unassigned, and Nmap has no service name for 8011 either. Its only real characteristic is its neighbourhood: it sits in the 8000-8100 band that people work through when they need one more HTTP listener, so a hit is most often an application's Nth web port rather than a defined protocol. Fingerprint it; the number carries no meaning.

## EXPOSURE

**Expose with care.** Unassigned means no protocol-level judgement is possible. If it answers HTTP, treat it like any other unproxied app port and check whether it expected to be private.

## CHECK

```sh
curl -sI http://TARGET:8011/
```
