Thank you for reminding me, Shane! My personal goal is to provide advice to users "who to call" because neither user or tech support lines want to waste time on issues they cannot fix. (ISP is not going to fix botched bank domain, and vice versa.) It should not (only) a diagnostics tool for DNS geeks! Let me elaborate: We at CZ.NIC experience what it is like to be registry (CZ), software vendor (Knot Resolver), and DNS support team (for Turris routers) at the same time... Based on this experience I came to conclusion that it would have tremendous value if we can split DNS problems to two coarse categories: far/local end problems. Of course more information is bonus for geeks. Ideally the error code should provide the client software with enough information to decide what message should be shown to end-user: a] inform your system/network admin/ISP - when a "local" problem is detected - examples: -- local time is likely off (. NS signature expired/not yet valid?!) -- everything times out -- everything is REFUSED (client blocked for abuse) b] inform site owner (your bank), do not call your ISP! - e.g. all auths return REFUSED, botched DNSSEC signatures, ... I can imagine 4 possibilities: 00 - do not call anyone (no-error messages) 01 - call network admin/ISP 10 - call domain owner 11 - call someone, we do not know what happened This obviously does not conflict with detailed information in current proposal, I have nothing against it. Does it seem useful to others? -- Petr Špaček @ CZ.NIC
