Does Cloudflare have any services that provide protection for CNAME cloaking?
Protection against what? If it’s Proxied, then it looks like an “A” record without revealing the destination hostname. But the destination has to be ok with that. Some won’t work if it doesn’t behave like a standard CNAME.
That’s a browser issue. It’s essentially a website masking external trackers within their own subdomain, which browsers typically wouldn’t mind because it’s coming from the same domain.
I believe NextDNS provides some level of protection for this as part of their “Block Disguised Third-Party Trackers” option…I was just curious if Cloudflare had anything similar.
That’s just a really big filter list of tracker hostnames. So you’re talking about Cloudflare’s 126.96.36.199 DNS service. Cloudflare doesn’t have a “Trackers” category, nor would I expect them to. It’s a very complex minefield.
