They mention you can use their DNS, if you pay them. Or, you could just use Cloudflare's free DNS. Plenty of benefits of using Cloudflare in front of Netlify -- such as full caching the static site on our edge so it doesn't even need to go back to Netlify's (Cloudfront) edge. Same goes for SSL termination at our edge, and the other performance features we can add on top of your Netlify site. There's no reason not to use both -- at the free plan if you'd like.
