Benefits of Custom QR Subdomain

Professional Appearance

Transform your QR code links from:

  • Generic: QRanalytica.com/abc123

  • To Professional: qr.yourdomain.com/abc123

Enhanced Brand Trust

When customers scan your QR code, they'll see your own domain name instead of a generic service URL, instantly building trust and recognition.

Setup Process

1. DNS Configuration

Add this single DNS record to your domain's settings:

Type: A
Host: qr
Value: 157.245.102.21

2. Step-by-Step DNS Setup

  1. Log into your domain provider (GoDaddy, Namecheap, Cloudflare, etc.)

  2. Find the DNS management section

  3. Click "Add Record" or "Add DNS Record"

  4. Select "A" as the record type

  5. Enter "qr" as the host/name

  6. Enter the QRanalytica.com IP address ( 157.245.102.21 )

  7. Save the record

3. Connect in QRanalytica.com

  1. Go to your QRanalytica.com dashboard

  2. Navigate to Settings → Custom Domain

  3. Enter your subdomain: qr.yourdomain.com

  4. Click "Verify Domain"

  5. Wait for verification (usually 15-60 minutes)

Verification Process

  1. Our system will automatically verify your DNS configuration

  2. Your custom subdomain will be activated automatically

Important Notes

  • Only the qr subdomain is supported (qr.yourdomain.com)

  • DNS changes may take up to 48 hours to fully propagate

  • HTTPS is automatically provided for your subdomain

  • All new QR codes will use your custom subdomain once activated

Troubleshooting

Common Issues

  1. Verification Failed

    • Double-check the A record is correctly set to "qr"

    • Verify the IP address matches our provided IP

    • Wait at least 15 minutes before trying again

  2. Domain Not Working

    • Ensure you entered exactly "qr" as the subdomain

    • Check for any typos in the domain name

    • Verify DNS propagation using online tools
