Multi-provider DNS
Secondary DNS means two or more vendors are listed as nameservers for the same zone, so either can answer (resilience against a provider outage). Split means different zones (for example the main domain and a delegated subdomain or brand domain) use different vendors. Both count as multi-provider.
How we measure: for every hostname we find the zone that holds it (walking up to the closest delegated subdomain or the domain apex) and read that zone's NS records over DNS-over-HTTPS. Nameserver names map to vendors. Methodology.
