Sorry the API would look like the one below, with DNSKEY, not RRSIG

Hello,

Thank you for the quick response. I created the measurement on RIPE atlas portal. Please find the below image for reference, every time I check the Set DO bit field. I’ve also used the Rest API and the measurement looks like this,

  "query_class": "IN",
  "query_type": "RRSIG",
  "query_argument": "example.com",
  "use_macros": false,
  "description": "DNS measurement to",

The measurement ID is 31426231. I query for DNSKEY records, have the do bit set in this and yet don’t get back the RRSIGs.

Hi,

DNSSEC OK flag is false in this measurement. See https://atlas.ripe.net/measurements/31426231/#general and then 'DNS Specific Settings'. Maybe something went wrong in the creation of the measurement. What tool did you use?
