Q: How does CloudFlare get in between the communication

Hi reddit,

how does CloudFlare (CF) get in between a request to a website for example.

If I do DNS queries on websites using CF I get back their server IPs. How do they forward the traffic to the intended website?

I couldn't find a deeper explanation. It just seems like you change your domains nameserver to CFs and you are good to go. But how does it actually work in detail?

Thanks in advance.
