Parallel multi-resolver DNS propagation & latency comparator for Linux
A parallel multi-resolver DNS propagation checker, consensus analyzer, and resolver response-time benchmark utility for Linux. A lightweight Linux alternative to NirSoft DNSDataView GUI for querying domains simultaneously across multiple public, system, custom, and DNS-over-HTTPS resolvers.
Key features:
- Queries target domains concurrently across Cloudflare (1.1.1.1 / 1.0.0.1), Google (8.8.8.8 / 8.8.4.4), Quad9 (9.9.9.9), OpenDNS (208.67.222.222), system /etc/resolv.conf nameservers, and RFC 8484 DNS-over-HTTPS (DoH) endpoints.
- Compares resource record sets (A, AAAA, MX, NS, CNAME, TXT, SOA, CAA) side-by-side to highlight unanimous consensus, GeoDNS split answers, and unpropagated or NXDOMAIN mismatches.
- Renders a live per-resolver round-trip latency (RTT ms) comparison bar chart with min, average, and max timings plus success rates.
- Supports customizable resolver profiles and exports detailed CSV and JSON DNS propagation audit reports.
