| OpenDNS | Users whose problem is closer to a public resolver with stronger enterprise and security-policy context | policy control, enterprise framing, and security context are more visible | If the real problem is closer to the default resolver inside the local access network, this side becomes a weak fit | Low-medium | Best as the OpenDNS path |
| ISP DNS | Users whose problem is closer to the default resolver inside the local access network | default access environment and local-network context are more visible | If the real problem is closer to a public resolver with stronger enterprise and security-policy context, this side becomes less convincing | Low-medium | Best as the ISP DNS path |
| Separate roles before ranking | Users who do not want both sides rewritten as the same kind of DNS | Service goals, deployment context, boundaries, and false-positive cost together | The workflow is longer, but it sharply reduces shallow comparison | Medium | Best as the final decision path |
