Updating DNS Records

Step-by-step instructions for changing your DNS records to point to AtomicEdge.

Step 1: Access Your DNS Provider

Popular DNS Providers

• Cloudflare - Most popular DNS service
• GoDaddy - Domain registrar with DNS management
• Namecheap - Domain registrar with DNS management
• Route 53 - Amazon's DNS service
• Google Domains - Google's domain service
• Your hosting provider - Often includes DNS management

Finding DNS Management

1. Log into your account with your domain registrar or DNS provider
2. Look for "DNS Management", "DNS Settings", or "Domain Management"
3. Select your domain if you have multiple domains

Can't find DNS settings? Contact your hosting provider or domain registrar for help.

Step 2: Choose Your Record Type

Option A: A Record (Recommended)

Best for most websites:

1. Find your A record for your domain (usually shows as @ or your domain name)
2. Change the IP address from your current server IP to your AtomicEdge WAF endpoint IP
3. Set TTL to 300 (5 minutes) for faster propagation
4. Save changes

Example A Record:

Record Type: A
Name: @ (or your domain)
Value: 198.51.100.10  ← Your AtomicEdge WAF IP
TTL: 300 (5 minutes)

Option B: CNAME Record

Alternative method using hostname:

1. Change your CNAME record to point to your AtomicEdge endpoint hostname
2. Set TTL to 300 (5 minutes)
3. Save changes

Example CNAME Record:

Record Type: CNAME  
Name: @ (or your domain)
Value: waf-endpoint-abc123.atomicedge.io
TTL: 300 (5 minutes)

Step 3: Update WWW Record

Protect Both Root and WWW

Most websites need both example.com and www.example.com to work:

For A Records:

@ → 198.51.100.10 (your AtomicEdge IP)
www → 198.51.100.10 (same AtomicEdge IP)

For CNAME Records:

@ → waf-endpoint-abc123.atomicedge.io
www → waf-endpoint-abc123.atomicedge.io

Step 4: Save and Wait

After Making Changes

1. Save your DNS changes
2. Wait for propagation (5-60 minutes typically)
3. Check your AtomicEdge dashboard for "Active" status
4. Test your website to ensure it loads normally

Propagation Times

• Minimum: 5-15 minutes
• Typical: 30-60 minutes
• Maximum: 24-48 hours (rare)

Common Configurations

Standard Website

Type: A, Name: @, Value: 198.51.100.10, TTL: 300
Type: A, Name: www, Value: 198.51.100.10, TTL: 300

Business Website with Email

Type: A, Name: @, Value: 198.51.100.10, TTL: 300
Type: A, Name: www, Value: 198.51.100.10, TTL: 300
Type: MX, Name: @, Value: mail.example.com, Priority: 10

Important Notes

Don't Change These Records

• MX Records - Email routing (leave unchanged)
• TXT Records - Domain verification (leave unchanged)
• NS Records - Name servers (leave unchanged unless instructed)

TTL Settings

• Set to 300 (5 minutes) before making changes for faster updates
• Can increase later to 3600 (1 hour) or higher for better performance

Next Steps

• Configure Subdomains - Set up blog, shop, etc.
• Verify DNS Changes - Confirm everything is working
• Troubleshoot Issues - Fix common problems
