Frequently Asked Questions
What are DNS records and why do they matter? ▼
DNS (Domain Name System) records are instructions stored in DNS zones that tell the internet how to handle traffic for your domain. They map domain names to IP addresses, configure email routing, verify domain ownership, and enable security features. Without properly configured DNS records, your website won't load, emails won't deliver, and security verification will fail.
What is the difference between an A record and an AAAA record? ▼
An A record maps a domain name to an IPv4 address (e.g. 192.168.1.1). An AAAA record maps a domain to an IPv6 address (e.g. 2001:0db8::1). Most websites have A records; AAAA records are used when your hosting provider supports IPv6. Both can exist simultaneously, and modern browsers will prefer IPv6 when available.
How do I verify my SPF, DKIM and DMARC records? ▼
Use the TXT record lookup for SPF and DMARC. SPF records start with "v=spf1" and are stored as TXT records on your root domain. DMARC records are TXT records located at "_dmarc.yourdomain.com". DKIM records are TXT records found at a selector subdomain like "selector._domainkey.yourdomain.com". All three work together to authenticate your email and prevent spoofing.
What is DNS propagation and how long does it take? ▼
DNS propagation is the time it takes for DNS record changes to spread across all DNS servers worldwide. This delay is controlled by the TTL (Time to Live) value set on each record. Most propagation completes within 1–4 hours, but can take up to 48 hours in rare cases. Lowering your TTL to 300 seconds (5 minutes) before making changes speeds up propagation significantly.
What is an MX record and how do I check it? ▼
An MX (Mail Exchange) record specifies which mail server handles incoming email for your domain. Each MX record has a priority value — lower numbers mean higher priority. To check your MX records, select "MX" from the record type dropdown and enter your domain. If your MX records are missing or misconfigured, emails sent to your domain will bounce or be lost.
