# WHATPORT(280)

## NAME

port 280 — http-mgmt — Registered as "http-mgmt" with no public specification — in practice just another HTTP admin port.

Protocol: TCP  
IANA: http-mgmt

## DESCRIPTION

IANA lists 280 as http-mgmt, assigned to Adrian Pell, but no protocol document was ever published for it and no widely deployed product claims the name. What actually turns up on 280 is ordinary HTTP: a device or appliance whose web management interface was moved off 80, or a proxy or admin console picking a low free port. Treat it as unidentified HTTP and confirm with a request rather than assuming the registration describes the listener.

## EXPOSURE

**Expose with care.** If this is a device management UI it is cleartext HTTP with a login form — fine on a management VLAN, never on a public address.

## CHECK

```sh
curl -sSI --max-time 5 http://TARGET:280/
```
