Cloudways offers managed cloud hosting for any size business to host a website or complex web applications.

CDN (Content Delivery Network) is one of the essential performance optimization components for any website. It accelerates content delivery by serving the request from the nearest locations of the users.

One of the frequent questions I receive is how to find out what CDN is used on a particular site?

We all love curiosity. Isn’t it?

Previously, I wrote about how to find the technologies being used on a site, and in this post, I’ll explain how to check the CDN.

There are two possible ways, so choose your preference.

Using Online Tools

Probably the quickest way to find is by using the tools. The following tools where you enter the domain name, and it gives you the CDN provider name.

CDN Finder

CDN Finder by CDN Planet gives you which provider is being used on an entire website or particular domain name.

Easy, isn’t it?


If the above tools don’t give you the results, then you can find it manually. It requires a little bit of effort, but you will get it.

First, you need to find out the IP address of the domain. You can use any of the following tools to get the IP address.

Ex: I got as A record of

Next, you need to find the IP owner with online tools.


As you can see, the IP is owned by Cloudflare. If you like to automate the process of getting IP, you can consider leveraging IP lookup API.

I hope this quick instruction helps you to check the CDN of any site for your research.
