DNSDrift

DNSDrift is a web app (with optional Slack/Teams alerts) that continuously monitors your domains and DNS records for unexpected changes, propagation anomalies, and risky misconfigurations. You connect domains via read-only DNS provider APIs (Cloudflare, Route 53, etc.) or by importing zone files, then set “known-good” baselines per environment (prod/staging). The app runs scheduled global resolvers checks, compares authoritative vs recursive answers, and flags drift: record edits, TTL drops, nameserver changes, CNAME flattening surprises, DMARC/SPF regressions, and accidental wildcard exposure. It also tracks certificate-related DNS (ACME challenges) and warns when changes could break renewals. This is not another generic DNS lookup tool; it’s a change-detection and incident-prevention layer that helps teams avoid outages caused by human error, vendor UI mistakes, or compromised registrar accounts.
