# NextDNS CNAME Cloaking Blocklist

A list of domains used by tracking companies as CNAME destination when disguising third-party trackers as first-party trackers.

> Read our article about this: [CNAME Cloaking, the dangerous disguise of third-party trackers](https://medium.com/nextdns/cname-cloaking-the-dangerous-disguise-of-third-party-trackers-195205dc522a).

**⚠️ For this list to work at all, the blocking logic needs to wildcard match (domain and all its multi-level subdomains) CNAMEs against the domains in this list.**

> Read about how we make this list work at NextDNS: [NextDNS first to support blocking of ALL third-party trackers disguised as first-party](https://medium.com/nextdns/nextdns-added-cname-uncloaking-support-becomes-the-first-cross-platform-solution-to-the-problem-e3f437f84342).
