# WHATPORT(48080)

## NAME

port 48080 — Unassigned (commonly an alternate HTTP listener) — Unregistered, but the digits spell "8080 with a 4 in front" — usually someone's second HTTP port.

Protocol: TCP  
IANA registry

## DESCRIPTION

There is no IANA assignment for 48080 and no service name in Nmap's database, which sees it open on about 0.04% of hosts. The number is a hand-picked variant of 8080, so an open port here is most often an extra HTTP listener — a second app server, a proxy, or a management UI moved off the obvious port. Port obscurity is not access control: a version scan finds it in seconds.

## EXPOSURE

**Expose with care.** Judge it as the HTTP service it usually is — cleartext with an admin UI behind it should not face the internet; a plain reverse-proxied app on TLS elsewhere is a different matter.

## CHECK

```sh
curl -sS -I -m 5 http://TARGET:48080/
```
