Why DNS matters
When email stops flowing or a website goes dark, the cause is frequently a DNS misconfiguration. Whether your zone lives at GoDaddy, Cloudflare, or Microsoft 365, the record types are the same.
The record types you'll actually touch
| Record | Purpose |
|---|---|
| A / AAAA | Points a hostname to an IPv4 / IPv6 address (your website). |
| CNAME | Alias one name to another (e.g., autodiscover, www). |
| MX | Directs email to your mail provider (Microsoft 365). |
| TXT / SPF | Lists servers allowed to send mail for your domain. |
| DKIM | Cryptographically signs outbound mail. |
| DMARC | Tells receivers what to do with mail that fails SPF/DKIM — and reports on it. |
The email-authentication trio
SPF, DKIM, and DMARC together are the single most effective defense against spoofing and the biggest factor in whether your legitimate email lands in the inbox. A missing DMARC policy is an open door for impersonation.
Common pitfall: when moving DNS between GoDaddy, Cloudflare, and Microsoft 365, records get orphaned. IDENETY audits and consolidates your zone so nothing breaks silently.
TTL & propagation
Lower TTLs before a migration so changes propagate quickly; raise them afterward for stability. IDENETY manages DNS as part of Microsoft 365 migrations and as a standalone service. Ask our engineers about a DNS audit.
