Overview

Package dns implements a DNS resolution health check using a minimal in-tree DNS client (no third-party dependency). For each target it queries one or more resolvers and flags: records that don't resolve, drift from an expected value, TTL below a threshold, and answers that diverge across resolvers (including SOA serial mismatches — a propagation problem).
