nb-f.dk is a registered .dk domain whose nameservers (ns4.dns-123.net, ns5.dns-123.net, ns6.dns-123.net) do not answer for it, so it is currently a lame delegation and does not resolve. It was registered on 7 December 2009 (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. |
