Add Domain

Add Domain

Adding a domain to Sundun CDN is the first step to accelerating and protecting your website. This guide walks you through the domain onboarding process.

Prerequisites

Before adding a domain, ensure you have:

• Access to your domain's DNS management panel
• Administrative rights to your Sundun account
• The domain is not already configured with another CDN provider (or you're ready to migrate)

Step 1: Navigate to Domain Management

1. Log in to your Sundun dashboard
2. Click Domains in the left sidebar
3. Click the Add Domain button in the top right corner

Step 2: Enter Domain Information

Enter your domain name in the input field. You can add domains in the following formats:

Note: Adding a root domain does not automatically protect subdomains. Add each subdomain separately or use a wildcard configuration.

Step 3: Select Service Plan

Choose the appropriate service plan for your domain:

• Starter: Basic CDN acceleration and DDoS protection
• Business: Advanced caching rules, WAF, and priority support
• Enterprise: Custom configurations, dedicated support, and SLA guarantees

Step 4: Configure Basic Settings

Acceleration Region

Select the acceleration regions based on your target audience:

┌─────────────────────────────────────────┐ │ Global - All regions │ │ Asia Pacific - APAC nodes only │ │ North America - NA nodes only │ │ Europe - EU nodes only │ │ Custom - Select specific PoPs │ └─────────────────────────────────────────┘

Protocol Support

Choose which protocols to support:

• HTTP only: Not recommended for production
• HTTPS only: Recommended for security
• HTTP and HTTPS: Supports both protocols

Step 5: Verify Domain Ownership

Before your domain can be activated, you must verify ownership using one of these methods:

Method 1: DNS TXT Record (Recommended)

Add a TXT record to your DNS:

Type: TXT Name: _Sundun-verify Value: Sundun-verification=abc123xyz TTL: 300

Method 2: DNS CNAME Record

Add a CNAME record to your DNS:

Type: CNAME Name: _Sundun-verify.example.com Value: verify.Sundun.com TTL: 300

Method 3: File Verification

Upload a verification file to your web server:

URL: https://example.com/.well-known/Sundun-verify.txt Content: Sundun-verification=abc123xyz

Step 6: Complete Setup

After verification succeeds:

1. Review your domain configuration summary
2. Click Confirm and Add Domain
3. You'll receive a CNAME record to point your domain to Sundun

Domain Status

After adding, your domain will show one of these statuses:

Next Steps

After successfully adding your domain:

1. Configure CNAME records to point traffic to Sundun
2. Set up HTTPS certificates for secure connections
3. Configure your origin server settings

Troubleshooting

Verification Failed

• Ensure DNS records have propagated (may take up to 48 hours)
• Check for typos in the verification value
• Verify you're adding records to the correct DNS zone

Domain Already Exists

If you see "Domain already exists" error:

• The domain may be added to another Sundun account
• Contact support with proof of domain ownership to transfer

API Reference

You can also add domains programmatically:

curl -X POST https://api.Sundun.com/v1/domains \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{"domain": "example.com", "plan": "business"}'
