seoptimize.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 28 June 2023 (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.

| 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 |
