Do I have to have the IP address of a server to initiate a DMCA takedown if the server is behind a service like Cloudflare?

MostlyCarbonite asked:

We have some content that is, well, “contested”. The site that is misusing our content is being hosted by Cloudflare. I’m concerned that I will need to know the IP address of the server hosting the content in order to issue a DMCA takedown. Does the DMCA have an allowance of some sort for proxied content? Do I have to know the IP address of the real server hosting the content?

My answer:

You should send your DMCA complaint to CloudFlare. Once they process it, they will tell you where the site is hosted, at which point you can serve the DMCA on the actual hosting provider.
