Cloudflare as Secondary

With incoming zone transfers, you can keep your primary DNS provider and use Cloudflare as a secondary DNS provider.

When you make edits in your primary DNS provider, those DNS records will be transferred from your primary DNS provider to Cloudflare via zone transfer using AXFR ↗ or IXFR ↗.
