What is DNS-OARC?

**DNS**-OARC (**DNS** Operations, Analysis, and Research Center) focuses on **DNS** infrastructure critical to email delivery. SPF, DKIM, DMARC, and MX records all depend on **DNS**. **DNS**-OARC ensures this foundational layer operates reliably.

Activities include: monitoring **DNS** health, researching **DNS** security issues, developing operational best practices, and coordinating response to **DNS**-based attacks. Their work indirectly supports email authentication by ensuring **DNS** queries resolve correctly.

For email practitioners, **DNS**-OARC resources help understand **DNS** requirements for authentication. Proper **DNS** configuration is fundamental to deliverability. **DNS**-OARC publications on TTLs, zone management, and **DNSSEC** inform best practices for maintaining email-related **DNS** records.
