gulbæk.dk is a registered .dk domain whose nameservers (ns.gullestrupnet.dk, ns2.gullestrupnet.dk) do not answer for it, so it is currently a lame delegation and does not resolve.

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.
