jakobsen-dk.dk is a registered .dk domain whose nameservers (ns1.avalonia.com, ns2.avalonia.com, ns3.avalonia.com) do not answer for it, so it is currently a lame delegation and does not resolve. It was registered on 7 October 1999 (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.
