That's not quite right; as the name suggests, it uses CNAMEs (which point to other records), not A records (which point to IPs). So you would have something like `media.q-company.example` as a CNAME to `q-company.ads-tracking.example` which then has an A record to give an IP. Browsers might not offer intermediate DNS names to extensions (I don't know), so something like uBlock might need to rely on IP lists, but DNS-based filtering like pihole should just block it by a rule against `ads-tracking.example`. In any case, it's good to use both browser based and DNS based malware blockers.
