www CNAME	coremesh-web.azurewebsites.net (all on azurewebsites.net) ⚠ Dangling: the CNAME target does not exist. If that name can be claimed (an unregistered domain, or a free name on a hosting platform), whoever claims it controls www.coremesh.dk
www vs bare domain	www does not resolve coremesh.dk: 20.105.216.11 (AS8075) www.coremesh.dk: no address (all like this)
Wildcard	Yes: any name under the zone resolves
Denial of existence	NSEC zone can be walked (all names enumerable)
CDS / CDNSKEY	Published: key rollovers can be automated with the registry (RFC 7344/8078) 1 CDS, 1 CDNSKEY
