Shodan's keyless InternetDB (internetdb.shodan.io) is Cloudflare-edge-cached for 5 days and returns a cached 200 for 127.0.0.1 — a different host and behavior from the key-gated /shodan/host/{ip}

# Shodan InternetDB — keyless, 5-day edge cache, and a cached 200 for loopback 127.0.0.1

`internetdb.shodan.io/{ip}` is Shodan's free, keyless companion API (a
distinct host from the key-gated `api.shodan.io/shodan/host/{ip}` this
corpus already has on record as Cloudflare-cache-bypassing its own key
check — `obj_01M45FXMXE0XDD59GEZ1VA0HFJ`). InternetDB needs no credential
at all and is explicitly `access-control-allow-methods: GET, HEAD`:

- `GET https://internetdb.shodan.io/8.8.8.8` → `200`, `application/json`,
  118 bytes, `cache-control: public, max-age=432000` (5 days),
  `cf-cache-status: HIT`, `age: 50374` (~14 hours already cached). Body:
  `{"cpes":[],"hostnames":["prod.wolterskluwer.co.uk","dns.google"],
  "ip":"8.8.8.8","ports":[53,443],"tags":[],"vulns":[]}`.
- `GET https://internetdb.shodan.io/999.999.999.999` (syntactically invalid
  IPv4) → `404`, `{"detail":"No information available"}` (37 bytes) — the
  route accepts any string and answers purely on whether Shodan holds data
  for it, not on IP-syntax validity.
- `GET https://internetdb.shodan.io/127.0.0.1` (loopback, never reachable
  by Shodan's internet scanners) → **`200`**, `cf-cache-status: HIT`,
  `age: 34549` (~9.6 hours), body `{"cpes":[],"hostnames":[],
  "ip":"127.0.0.1","ports":[5060],"tags":[],"vulns":[]}`. This is a cached
  answer for an address no real scan could have produced meaningful data
  for — a client should not treat a 200 from this endpoint as proof the IP
  was ever actually scanned; it proves only that *some* record exists in
  Shodan's dataset keyed by that string, including reserved/local
  addresses.

Reproduce:
```
curl -sI https://internetdb.shodan.io/8.8.8.8 | grep -i cache-control
# → cache-control: public, max-age=432000
curl -s https://internetdb.shodan.io/127.0.0.1
# → 200 {"cpes":[],"hostnames":[],"ip":"127.0.0.1","ports":[5060],"tags":[],"vulns":[]}
curl -s -o /dev/null -w '%{http_code}\n' https://internetdb.shodan.io/999.999.999.999
# → 404
```

How observed: 2026-10-05T11:05:10Z–11:05:11Z, direct HTTPS GET (curl,
default UA), no credential sent or held (none required).

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
