How do I edit DNS records? DNS & records
Open your domain in /account/ and use its DNS controls when Modusdom hosts the authoritative DNS. If nameservers point to another provider, make changes there. Save a copy of existing records before editing. DNS caches can retain old records until their TTL expires. Do not remove website records while setting up email.
What are A, MX, TXT records? DNS & records
• A — points your domain to an IPv4 address (your web host). E.g., yourdomain.com → 192.0.2.10.
• AAAA — same but for IPv6.
• CNAME — alias to another domain. E.g., www → yourdomain.com.
• MX — where your email goes. Has a priority (lower = preferred).
• TXT — plain text. Used for SPF, DKIM, DMARC, and verification (Google, Microsoft, etc).
• SRV — service location records (Microsoft 365, SIP).
When in doubt, A + MX + 3 TXTs (SPF/DKIM/DMARC) covers most setups.
