# WHATPORT(3325)

## NAME

port 3325 — active-net (Active Networks) — Last port of the 3322-3325 Active Networks block; the registration is the whole public record.

Protocol: TCP  
IANA registry

## DESCRIPTION

3325 closes IANA's `active-net` range, registered to Bob Braden for the DARPA Active Networks programme. As with the other three ports in the block there is no protocol document, no reference implementation and no measurable deployment — the name exists in /etc/services and nowhere else that matters. Treat a scanner's `active-net` on 3325 as a lookup of the port number, not as identification of the service.

## EXPOSURE

**Expose with care.** Unknown service by default: fingerprint what is listening before deciding on exposure.

## CHECK

```sh
nc -vz TARGET 3325
```
