As the title suggests, my domain is registered with Route53 and until earlier this week, the DNS was managed there as well. LetsEncrypt was having issues confirming my ownership with that setup, so I moved the DNS to Netlify with dns1.p01.nsone.net, etc.
LetsEncrypt is peachy now, at least for the next 90 days.
How do I use the Netlify DNS to point a subdomain away from Netlify? I tried to add it as a subdomain in the control panel and it just points to my main site.
