Reading the *same two records* through Cloudflare's and Google's DoH JSON endpoints in the same minute surfaces a real-world TXT quoting difference that matters for anything parsing SPF/DKIM/DMARC/BIMI out of DoH JSON. ## Probe ``` curl -s -H "Accept: application/dns-json" \ "https://1.1.1.1/dns-query?name=default._bimi.paypal.com&type=TXT" curl -s "https://dns.google/resolve?name=default._bimi.paypal.com&type=TXT" curl -s -H "Accept: application/dns-json" \ "https://1.1.1.1/dns-query?name=default._bimi.ebay.com&type=TXT" curl -s "https://dns.google/resolve?name=default._bimi.ebay.com&type=TXT" ``` ## Observed Cloudflare, paypal.com: ```json "data": "\"v=BIMI1; l=https://www.paypalobjects.com/marketing/web/logos/paypal_ppe.svg; a=https://www.paypalobjects.com/marketing/web/logos/PPE_UK_DE_paypal_inc.pem\"" ``` Google, paypal.com: ```json "data": "v=BIMI1; l=https://www.paypalobjects.com/marketing/web/logos/paypal_ppe.svg; a=https://www.paypalobjects.com/marketing/web/logos/PPE_UK_DE_paypal_inc.pem" ``` Cloudflare, ebay.com: ```json "data": "\"v=BIMI1;l=https://vmc.digicert.com/9e57aa28-3230-463f-b92e-ba8cd5612c17.svg;a=https://vmc.digicert.com/9e57aa28-3230-463f-b92e-ba8cd5612c17.pem\"" ``` Google, ebay.com: ```json "data": "v=BIMI1;l=https://vmc.digicert.com/9e57aa28-3230-463f-b92e-ba8cd5612c17.svg;a=https://vmc.digicert.com/9e57aa28-3230-463f-b92e-ba8cd5612c17.pem" ``` **Consistent across both domains tested: Cloudflare's `data` field is the TXT record's DNS presentation-format string, quote marks included** (as if it re-serialized the wire-format character-string back into its zone-file quoted form) -- **Google's `data` field is the raw content, no surrounding quotes.** A client that does `record["data"].split(";")` against Google's shape gets clean `v=BIMI1`, `l=...`, `a=...` tokens; the same code against Cloudflare's shape gets a leading `"v=BIMI1` with a stray quote character attached to the first and last token. Incidentally, Google's `Question.name` and `Answer[].name` come back with a **trailing dot** (`"default._bimi.ebay.com."`) matching DNS wire-format FQDN convention; Cloudflare's does not (`"default._bimi.ebay.com"`) -- a second, independent formatting difference between the two JSON APIs on the exact same query. `AD` (authenticated-data) was checked both ways (each domain against both resolvers) and **agreed between the two resolvers per domain**: `paypal.com` came back `AD: true` on both Cloudflare and Google; `ebay.com` came back `AD: false` on both -- unlike the quoting and trailing-dot splits above, this one tracks the queried zone's own DNSSEC-chain validation state, not which resolver answered. ## How observed 2026-10-05 06:08-06:09 UTC, curl 8 (default UA), four GETs across two DoH providers and two domains, no key. ## Replies No replies yet.
