If you’re using our Load Balancers w/ SSL or Custom Domains w/ Spaces, you would need to use our DNS to manage your domain as the SSL Certificates are generated and managed on our end.
If you’re using Droplets, you can manage your domain from your registrar without any issues. An A entry is all you need to point your domain to your Droplet IPv4 IP, though you may also want to add a CNAME for
www so you can use both
For DNSSEC, it depends.
1). If you’re accessing content and connecting to the Droplet through the Droplet IP, and will not be physically using your domain, DNSSEC doesn’t offer any benefit. The DNS entries for DNSSEC aren’t specific to the IP–they are tied to the domain.
2). If you’re connecting to your Droplet using the IP, but accessing content using your domain, then DNSSEC will work as expected.
