When an in-bailiwick nameserver cannot be resolved (no glue records and
iterative resolution fails), the traversal previously returned a generic
RespError. This made the Results section show many identical '6.7%
resulted in an error' lines and the Summary show '100% resulted in an
error' — even though the domain itself may be perfectly reachable in
practice via glue held by the registry.
Add a new RespNSResolutionFailed response type (string: ns_error)
for this specific case. Changes:
- traverse/response.go: add RespNSResolutionFailed, include it in
IsTerminal() and String()
- traverse/traverser.go: use RespNSResolutionFailed with a descriptive
ErrorMessage when ResolveNS fails in processReferral
- output/stats.go: map ns_error to nameserver lookup failed in
summaryTypeLabel
- output/text.go: handle RespNSResolutionFailed in formatResultLine
Before:
Results: 6.7% resulted in an error (x15)
Summary: 100% resulted in an error
After:
Results: 6.7% nameserver ns-a.hansenits.com.au could not be resolved (x15)
Summary: 100% nameserver lookup failed
