DNS (Domain Name System) is often called the "phonebook of the internet". When you type a website address like www.yourdomain.com into your browser, DNS translates this human-friendly name into the numerical IP address (like 192.168.1.1) that computers use to locate the website's server. Without DNS, you'd need to remember complex number sequences for every site you visit.

DNS management refers to the control and configuration of these translation records for your domain. Through your hosting provider's control panel, you can modify various DNS records that determine how your domain behaves:

• A Record: Points your domain to an IPv4 address
• AAAA Record: Points your domain to an IPv6 address
• CNAME Record: Creates an alias from one domain to another
• MX Record: Directs email to your mail servers
• TXT Record: Stores text information, often for verification

When you change hosting providers or add services like email or CDN, you'll need to update your DNS records. Important: DNS changes can take 24-48 hours to propagate globally, so plan accordingly. Always double-check your entries before saving, as incorrect settings can make your website or email inaccessible.

Most hosting providers offer intuitive DNS management interfaces with pre-configured templates for common setups. If you're unsure about specific settings, consult your provider's documentation or support team before making changes that could disrupt your online presence.
