❓ Frequently Asked Questions

Everything you need to know about DNS Lookup

What is DNS?+
DNS (Domain Name System) translates domain names to IP addresses. example.com → 93.184.216.34. Without DNS, you'd need to remember IPs.
What are different DNS record types?+
A = IPv4 address. AAAA = IPv6. MX = email server. TXT = text (SPF, DKIM, verification). NS = name servers. CNAME = alias.
Why check DNS records?+
Verify website setup, debug email delivery (MX), check Google Site Verification (TXT), troubleshoot domain issues, SEO audits.
What are A records used for?+
A records point your domain to a server's IPv4 address. Most fundamental DNS record - without this, your website doesn't load.
What are MX records?+
MX records direct email to mail servers. Multiple MX records = backup mail servers. Without MX, email to your domain won't deliver.
Why are TXT records important?+
TXT records hold: SPF (email security), DKIM (email signing), domain verification (Google, Bing, GitHub). Crucial for email deliverability.
What are NS records?+
Name Server records specify which DNS servers manage your domain. Pointing NS to Cloudflare = use Cloudflare DNS. Critical for DNS management.
How long do DNS changes take?+
TTL (Time To Live) controls. Default 1-24 hours. Short TTL = faster propagation but more queries. Long TTL = slower changes but better cache.
What is DNS propagation?+
When you change DNS, ISPs worldwide cache old records. Propagation = waiting for caches to expire. Can take 24-48 hours globally.
How to test DNS for new domain?+
After registering, set NS records first, then A records for hosting. Check with our tool. If empty, wait 1-4 hours and recheck.
What's difference between A record and CNAME?+
A points domain to IP directly. CNAME points domain to another domain. Use A for root domain, CNAME for subdomains pointing to services.
Can I have multiple A records?+
Yes! Multiple A records create round-robin DNS for load balancing. Browsers pick one randomly. Used for high-availability setups.
