DNS Security for Shopify Merchants

What is DNS?

DNS (Domain Name System) translates human-readable domain names like yourstore.com into IP addresses that computers use to communicate. Think of it as the phone book of the internet—when a customer types your store URL, DNS tells their browser where to find your actual website.

Why DNS Security Matters for Shopify Merchants

Your domain is your brand identity online. Misconfigured DNS can allow attackers to:

• Redirect your customers to fake versions of your store
• Intercept emails meant for your business
• Create convincing phishing sites using your domain’s reputation

For Shopify merchants, this directly impacts revenue and customer trust.

Common DNS Risks

1. DNS Hijacking

Attackers redirect traffic from your legitimate domain to fake sites. Customers think they’re on your store but are actually giving payment info to criminals.

2. Subdomain Takeover

Abandoned subdomains (like old-campaign.yourstore.com) can be claimed by attackers if the underlying service is deleted but DNS records remain.

3. Missing SPF/DKIM

Without proper email authentication records, anyone can send emails pretending to be from your domain.

How to Check Your DNS Configuration

1. Visit your domain registrar dashboard (GoDaddy, Namecheap, Cloudflare, etc.)
2. Review your A, CNAME, MX, and TXT records
3. Verify SPF, DKIM, and DMARC records exist and are correctly configured
4. Check for any unused subdomains pointing to decommissioned services
