| Public DNS | Users whose question is closer to recursive and public-resolution service | DNS query path, client configuration, and resolution context are stronger | If the real question is closer to website frontage, caching, and edge-access network, this side becomes misleading | Low-medium | Best as the Public DNS path |
| CDN and edge Anycast | Users whose question is closer to website frontage, caching, and edge-access network | HTTP and HTTPS access, caching, security proxying, and site-fronting context are stronger | If the real question is closer to recursive and public-resolution service, it will mislabel the role | Low-medium | Best as the CDN and edge Anycast path |
| Boundary cross-check | Users who need false-positive control | Both sides may use Anycast, global edge nodes, and the same umbrella-brand infrastructure; then inspect protocol, usage, and observation entry point | It is slower, but prevents the page from collapsing into a slogan | Medium | Best as the final judgment layer |
