You need to put in the herokudns.com address that the CNAME is pointing at – e.g. stark-wisteria-rnbgkawldfk6gq7m8308ytts.herokudns.com in our case.

  For me the securitytrails.com website just crashes. I put my DNS target: "stark-horse-mrp4jeowu9yvwpnnma32x6hd.herokudns.com", clicked "Run Check" and it seems to redirect to a failed (no CSS) webpage. Anyone else experiencing this? EDIT: I MANAGED to make it work with this: https://www.nslookup.io/ https://www.nslookup.io/ Make sure to go through all the tabs at the top (Cloudflare DNS, Google DNS) - for me they were all "no A records found". Only "Authoritative" gave me 3 A records which I successfully managed to use.

    Yeah securitytrails.com was working for me, but went down about 10 mins ago.

    That seems to happen when you put in a DNS target that doesn't have any records in SecurityTrails. In that case, it is best to use nslookup

  Thanks so much, it worked for us.
