Client-Side CloudFront IP Testing

Test connection times directly to CloudFront IPs. Each request goes to https://[IP_ADDRESS] to measure actual network performance.

CloudFront IP Speed Tester
Test connection times directly to CloudFront IPs from your browser

Testing 0 CloudFront ranges with 20 random IPs.

How this works: This test makes direct requests to randomly selected CloudFront IP addresses to measure connection latency.

How to use these results: The fastest IP addresses can be used in your DNS configuration to potentially improve connection times.

Note: IP ranges are fetched from the CloudFront IP list tool and include detailed location and AS number information.

Current Domain Baseline Test

Test your current domain performance as a baseline for comparison.

Server-Side CloudFront IP Tester
Test CloudFront IPs with your domain using server-side requests (more accurate)

Note: Due to browser security restrictions, the server-side testing may not work in all environments. If you encounter errors, please use the client-side testing instead.

Alternative: For the most accurate results, consider running similar tests from your server environment using tools like curl or wget.
