Cloudflare provides a CDN service which can speed up the websites. While using the free plan, you could not choose the nodes of the CDN. However, The cloudflare partner project allows users to use cname to get their websites into the CDN, which means users can choose whichever nodes they like.

There are some situations that you only want to speed up your websites at your location. I will tell you how to use Python to choose the the ip that suits you best.

Cloudflare has a ip list of their CDN, which can be obtained at here. The method that i use is very simple:

1. Ping the IPs and get the latency and loss.
2. Choose the best IP.
3. Use Cloudflare Partner Project to cname your domain to the chosen ip.

python pingip.py

You will get a log file in your current directory.

In pingip.py file. You could change:

• the number of threads to fit the performance of your computer and your network capacity.
• the THRESHOLD under which the ip and latency will be logged into the log file.

If you are using windows 10 x64. You can directly use the package I packed, It can be found [here].(https://github.com/olixu/cloudflare-ip-ping/releases)

You could open an issue and upload your log file, tell me whether this script works or not, please attach your location and your network supplier.
