  "whatItIs": "IANA assigns 3322 through 3325 as a single block named `active-net`, \"Active Networks\", registered by Bob Braden of ISI for the DARPA active-networking research programme of the late 1990s — the idea that packets could carry code for routers to execute. The work produced papers and prototypes, not a deployed protocol, and no public specification ties a particular function to 3322. Scanners label it `active-net` from the registry alone. Anything listening here today is unrelated to the registration.",

    "verdict": "careful",
    "note": "Treat an open 3322 as an unidentified service and fingerprint it; the registered name tells you nothing about what is actually answering."
