osatleter.dk is a registered .dk domain whose nameservers (ns1.simply.com, ns2.simply.com, ns3.simply.com) do not answer for it, so it is currently a lame delegation and does not resolve. It was registered on 7 September 2025 (WHOIS) and was already in the .dk zone when our tracking began on 16 June 2026. Below are all of its DNS records from this scan: nameservers, A/AAAA, MX, TXT, SPF, DMARC, CAA, TLSA/DANE, MTA-STS, SRV and more.
| www | Address record (no CNAME) |
| Wildcard | Yes: any name under the zone resolves |
| Denial of existence | NSEC zone can be walked (all names enumerable) |
| CDS / CDNSKEY | Published: key rollovers can be automated with the registry (RFC 7344/8078) 1 CDS, 1 CDNSKEY |

| Validation Status | ⚠️ Bogus — the parent still publishes a DS record, but the delegated nameservers don't answer, so no signed answer can be fetched. The zone isn't serving broken signatures; it isn't serving at all. |
| AD Flag (resolver validates) | ✗ Not set |
| DS Record | ✓ Found |
| DNSKEY Record | ✗ Not found |
| Flags | resolution failed: failure |
