c1.dk is a registered .dk domain whose nameservers (ns1.proisp.no, ns2.proisp.no) do not answer for it, so it is currently a lame delegation and does not resolve. It was registered on 24 October 2002 (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.
