optimalcare.dk is a registered .dk domain whose nameservers (ns.dandomain.dk, ns2.dandomain.dk) do not answer for it, so it is currently a lame delegation and does not resolve. It was registered on 7 September 2019 (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.

AD Flag (resolver validates)	✗ Not set
DS Record	✓ Found
DNSKEY Record	✗ Not found
Flags	resolution failed: failure
