sip03.dk is a .dk domain the registry has taken out of service: it is delegated to the registry's own sentinel nameservers (nonexistent.punktum.dk), so it does not resolve. It was registered on 4 October 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 our latest scan: nameservers, A/AAAA, MX, TXT, SPF, DMARC, CAA, TLSA/DANE, MTA-STS, SRV and more.
