| www CNAME | tap.local (all on tap.local) ⚠ 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.tanzu.dk |
| www vs bare domain | Neither resolves tanzu.dk: no address www.tanzu.dk: no address |
| Wildcard | Yes: any name under the zone resolves |
