Many people seem to think that Cuckflare helps to protect against DDoS attacks. This is, in fact, incredibly easy to circumvent.
Cuckflare "protects" against DDoS by basically being a DNS-enforced MitM of you and the site it "protects". Therefore, finding the real IP address would enable one to circumvent the DDoS "protection".
The real IP address can be found easily for any website. First you need a tool which scans lots of IP addresses quickly. zmap is a reasonable choice. Then, you need to scan port 80 or 443 (depending on the site) and obtain a list of all addresses with those ports open. Afterwards, you download the front page of each of those (zgrab does it quickly) and search for a unique string only appearing in the site you target. This will net you the IP address of the site, which you can then attack at any time.
If you know the country the site is hosted in, that makes the scan even quicker and easier because you only need to scan a subset of all the possible IP addresses.
Someone give me a site which uses cuckflare which you want to obtain the real IP of; I can't think of any besides 8chan but we already know the real IP of that.
