So I bought a domain from 1&1 that wasn't available to Wix or Digital Ocean. I currently have my domain DNS currently pointing to Wix. Which will be the homepage. I want to host a mumble off of a DO droplet. Would I just need to add DO's name servers as secondaries along with the Wix? Then make a subdomain and point the DNS to my droplet?
