 Warning: We strongly recommend that you do not use wildcard DNS records, such as `*.example.com`. These records put you at an immediate risk of domain takeovers, even if you verify the domain. For example, if you verify example.com this prevents someone from using `a.example.com`, but they could still take over `b.a.example.com` (which is covered by the wildcard DNS record).
