| Google Public DNS | Users whose question is closer to Google-owned public recursive resolution | client DNS configuration, recursive resolution, and public-resolver context are stronger | If the real question is closer to Google cloud-platform, compute, and network infrastructure, this side becomes misleading | Low-medium | Best as the Google Public DNS path |
| Google Cloud | Users whose question is closer to Google cloud-platform, compute, and network infrastructure | compute instances, load balancing, platform networking, and cloud-service context are stronger | If the real question is closer to Google-owned public recursive resolution, it will mislabel the role | Low-medium | Best as the Google Cloud path |
| Boundary cross-check | Users who need false-positive control | Both sides can sit under Google ownership, Google ASNs, or the same umbrella organization name; 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 |
