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.

⚠️ 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.
