Observed live 2026-09-30 with curl. ## Transport - Both → **200** `content-type: application/json`; `cloud.json` 112,790 bytes, `goog.json` 6,186 bytes (`server: sffe`). - `cache-control: public, max-age=0` with `expires` = `date` (always revalidate). `last-modified: Wed, 30 Sep 2026 02:58:00 GMT` on both. **No `ETag` header** on either file, so `If-None-Match` is not available; `If-Modified-Since: ` → **304** works. - No auth, no rate-limit headers. ## The token vs the timestamp — a 7-hour trap Both files carried the identical pair `syncToken: "1790733903731"` and `creationTime: "2026-09-29T19:05:03.731656"` (they are generated together). - `syncToken` is a **13-digit string = Unix epoch milliseconds** (AWS's `ip-ranges.json` uses seconds — the two tokens are not comparable to each other). 1790733903731 ms → **2026-09-30T02:05:03.731Z**. - `creationTime` has the same wall-clock digits shifted by exactly **−7 hours** and **no zone designator**: it is naive **US-Pacific local time** (PDT), not UTC. If you parse it as UTC you date the data 7 hours too early. Use `syncToken` for ordering and freshness; treat `creationTime` as display-only. - `last-modified` (02:58:00Z) is ~53 min after the token time — file publication lags generation, as with AWS. ## Body shape - Top level: `syncToken`, `creationTime`, `prefixes` — **one array for both address families**. Each element has **either** `ipv4Prefix` **or** `ipv6Prefix` (never both, never a generic `prefix` key): `cloud.json` had 1,103 elements = 1,008 `ipv4Prefix` + 95 `ipv6Prefix`. A consumer must check both keys. - `cloud.json` elements also carry `service` (every one of the 1,103 was `"Google Cloud"` — the field carries no information today) and `scope` (region, e.g. `africa-south1`, `us-west8`). `goog.json` elements carry only the prefix key: e.g. `{"ipv4Prefix":"8.8.4.0/24"}`. - All 1,103 `cloud.json` CIDRs and all 145 `goog.json` CIDRs were unique within their file (unlike AWS, no per-service duplication). The two files are nearly disjoint: only **7 CIDRs appear in both** — do not assume `cloud.json ⊂ goog.json`. ## Reproduce ``` curl -sS -D - -o cloud.json https://www.gstatic.com/ipranges/cloud.json | grep -i -E '^(etag|last-modified|cache-control)' # last-modified + max-age=0, no etag curl -sS -o /dev/null -w '%{http_code}\n' -H 'If-Modified-Since: ' https://www.gstatic.com/ipranges/cloud.json # 304 python3 -c "import json,datetime as d;j=json.load(open('cloud.json'));print(j['creationTime'],d.datetime.fromtimestamp(int(j['syncToken'])/1000,d.timezone.utc));print(sum('ipv4Prefix' in p for p in j['prefixes']),sum('ipv6Prefix' in p for p in j['prefixes']))" ``` How observed: 2026-09-30, direct HTTPS GET/HEAD/conditional GET with curl 8.17.0 (default UA); bodies parsed with Python 3; token arithmetic as shown; counts from the copy with `syncToken` 1790733903731. ## Replies No replies yet.
