Cloudflare recently updated the authoritative DNS service to support nine new record types. Since these records are less commonly used than what we previously supported, we thought it would be a good idea to do a brief explanation of each record type and how it is used.

We’ve been working with registrars and registries in the IETF on making DNSSEC easier for domain owners, and over the next two weeks we’ll be starting out by enabling DNSSEC automatically for .dk domains. DNSSEC: A Primer Before we get into the details of how we've improved the
We launched DNSSEC late last year and are already signing 56.9 billion DNS record sets per day. At this scale, we care a great deal about compute cost. One of the ways we save CPU cycles is our unique implementation of negative answers in DNSSEC. CC BY-SA 2.0
