A simple bash script that verifies whether domains are properly configured to point to Netlify's hosting infrastructure.

This utility checks a list of domains to determine if they're pointing to Netlify servers by examining their DNS records. It's useful for:

• Auditing multiple domains at once
• Verifying Netlify migrations
• Monitoring DNS configurations
• Troubleshooting hosting issues

• 🔍 Batch DNS checking for multiple domains
• ✅ Clear visual indicators for DNS status
• 🚀 Fast DNS lookups using dig
• 📋 Simple text file input format
• 🎨 Color-coded terminal output

• Bash shell
• dig command (usually included with dnsutils or bind-utils package)

1. Clone the repository:

git clone https://github.com/yourusername/script-check-netlify-dns.git
cd script-check-netlify-dns

2. Make the script executable:

chmod +x check_netlify.sh

1. Add your domains to domains.txt (one per line):

example.com
another-site.com
my-blog.org

2. Run the checker:

./check_netlify.sh

You can specify a different domain file:

./check_netlify.sh custom-domains.txt

The script provides color-coded output for each domain:

• ✅ Green: Domain points to Netlify
• 🟡 Yellow: Domain has DNS records but doesn't point to Netlify
• ❌ Red: No DNS records found

Example output:

Checking DNS for domains...

Checking example.com... ✅ Points to Netlify
Checking another-site.com... 🟡 Does not point to Netlify
Checking my-blog.org... ❌ No DNS records found

Checked 3 domains

The script identifies Netlify-hosted domains by checking:

1. CNAME Records: Looks for records ending with netlify.com.
2. A Records: Matches against known Netlify IP addresses:
   • 75.2.60.5
   • 99.83.231.61
   • 100.28.201.155
   • 34.234.106.80
