DNS (Domain Name System) is what connects your domain name to your actual website and email servers. Nameservers tell the internet which server holds your DNS records. Common DNS record types include: A Record (points your domain to a server's IP address), CNAME (points a subdomain to another domain), MX (routes your email), and TXT (used for verification like SPF/DKIM). You can manage all of this from Admin/Customer DNS settings. If you're unsure what to change, our support team can guide you — incorrect DNS changes can take your website or email offline.
