What is DNS Record?
DNS records are the internet's address book entries for your domain. An A record points the domain to a server's IP address; CNAME points one name at another; MX records route your email; TXT records hold verification codes and email-security policies like SPF and DKIM. When someone types your website address, DNS records tell their browser which server to contact.
Every business owner eventually touches DNS: pointing a new domain at hosting (A record), setting up Google Workspace or Zoho Mail (MX records), verifying the domain for Google Search Console or the WhatsApp API (TXT record), or connecting a subdomain to a SaaS product (CNAME). Changes propagate worldwide in minutes to 48 hours, which is why developers say "wait for DNS" after migrations.
