Question 1

What does a DNS health check cover?

Accepted Answer

It checks nameserver configuration, A/AAAA records, MX records, email authentication (SPF, DKIM, DMARC), SOA record settings, and flags any misconfigurations or missing records.

Question 2

Why does my DNS health check show warnings?

Accepted Answer

Common warnings include missing SPF/DMARC records, low TTL values, nameservers all in the same network (no geographic diversity), or DNSSEC not enabled. Warnings aren't failures — they're recommendations.

Question 3

How often should I check DNS health?

Accepted Answer

After any DNS change, when migrating hosting/email providers, and periodically (quarterly). Regular checks catch expiring records, removed configurations, and drift from best practices.
