Domain + DNS Management

I run my own domains, so DNS isn't abstract to me. It's something I configure, debug, and occasionally get paged by.

mergedcloud.de (this site) sits on GitHub Pages behind a custom domain, which means CNAME/apex records and the occasional propagation-delay debugging session. Klar is split across klarsocial.de and klarsocial.eu; two different top-level domains for the same app, which meant thinking through cross-site auth as much as the DNS side of pointing both domains at the right infrastructure.

Beyond my own projects, this overlaps with domain and DNS work I do professionally: Zone files, record types, and making sure a domain change doesn't take a service down.
