Did you want domain registration, or just DNS management? Those are two very different services. They offer the latter but not the former. So while you (generally) have to buy domains elsewhere, you can then manage them entirely within Azure after doing so.

They also offer the former. It is called App Domains. (As Domains are AD domains)

Ive been using it for 3 years now to register names for my job as Azure bill just gets paid. Anything outside Azure is a bureaucratic mess.
