Domain IP setup in Cloudflare different from the IP showing up inWhatsmydns.net

Anyone knows why? Please see attached screenshots.

This tutorial explains why, when doing a DNS lookup on your domain, you may see IP addresses that are different to those you specified in your DNS records. What are the addresses I see?

Hi @genius1,

As explained in the tutorial shared by @domjh, Cloudflare sits between your server and the visitors, so that bots (specially malicious bots) hit Cloudflare first, where they can hopefully be stopped. One of the important aspects of website security then is not revealing your origin server’s IP address, as it may be used to bypass Cloudflare. For that reason, I’d suggest you edit your original post to erase the IP address of your origin, as well as removing/editing the image that also reveals it.
