tehran.dk is a registered .dk domain whose nameservers (dns1.supremedns.com, dns2.supremedns.com, dns3.supremedns.com and 1 more) do not answer for it, so it is currently a lame delegation and does not resolve. It was registered on 23 February 2010 (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. |
