# WHATPORT(3324)

## NAME

port 3324 — active-net (Active Networks) — Third port of the Active Networks 3322-3325 reservation; unused in practice.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA lists 3324 only as part of the `active-net` block 3322-3325, Active Networks, registered by Bob Braden at ISI. The registration predates the modern registry's requirement for a contactable specification, and no active-networking implementation ever reached deployment, so the entry survives as a historical marker. Nothing in common use listens on 3324. Whatever you find there was configured by hand and should be identified directly.

## EXPOSURE

**Expose with care.** An open 3324 is an unidentified listener; fingerprint it rather than trusting the `active-net` label a scanner prints.

## CHECK

```sh
nc -vz TARGET 3324
```
