Protecting the real IP address of a website is essential to prevent DDoS attacks. There are multiple ways to find out the website’s IP address like Domain into IP or DNS records lookup. However, if you are using cloud-based security, proxy, or DNS based service, then it’s a little tricky to get the actual IP. But it’s difficult, not impossible. Let’s find out…

Censys

Censys search engine allows the researcher to find how websites are deployed with possible to reveal the IP address as well. It’s an exciting tool to find out not just the IP but many other things, including following.

I was able to find the real IP address of one of my sites which is on shared hosting.

Zoomeye was able to detect origin IP of a site behind Cloudflare, which is hosted on Google Cloud. Amazing!

SecurityTrails

As the name suggests, SecurityTrails let you find out current and historical data of A, AAAA, MX, NS, SOA, and TXT records. This can be handy to find out the real server’s IP when the website was running directly on the server’s IP and later was moved to CDN or cloud-based security provider.

Find Virtual Hosts

Find Virtual Hosts by Pentest-Tools will be helpful when you are looking to find the websites configured on a single IP.

They are discovered using a public search engine, DNS resolution, and searching for SSL certificates.
