Facts

Purpose: DNSViz visualizes DNS zone status to help understand and troubleshoot DNSSEC deployment, showing the DNSSEC authentication chain, resolution path, and detected configuration errors.dnsviz.net · 2 Oct 2026
Maintenance status: The web service is in maintenance mode: it can run new analyses but cannot load historical analyses or save new ones to its database.dnsviz.net · 2 Oct 2026
DNSSEC graph: Its visualization covers zones, delegations, resource record sets, negative responses, DNSKEY and DS records, NSEC/NSEC3, signatures, CDNSKEY/CDS, wildcards, node status, warnings, and errors.dnsviz.net · 2 Oct 2026
Validation status: The graph classifies DNS data as secure, bogus, or insecure based on whether a chain of trust exists from a trust anchor.dnsviz.net · 2 Oct 2026
Command line: The command-line suite includes probe, grok, graph, print, and query subcommands for querying DNS, assessing results, and producing graph or text output.github.com · 2 Oct 2026
Analysis inputs: The probe command accepts one or more domain names and queries recursive resolvers by default or authoritative servers when requested, serializing results as JSON.github.com · 2 Oct 2026
Output formats: The graph command can produce an image, a DOT graph, or an HTML file from serialized query results.github.com · 2 Oct 2026
Container: A Docker container is available, and the project documents running DNSViz commands inside it.github.com · 2 Oct 2026
Installation: The project README lists installation through package repositories including Debian, Ubuntu, Fedora, Gentoo, FreeBSD, and EPEL for specified RHEL and CentOS versions, as well as macOS through Homebrew or MacPorts.github.com · 2 Oct 2026
Dependencies: The README lists Python, dnspython, pygraphviz, and cryptography as dependencies; Graphviz and OpenSSL are examples of non-Python dependencies that may need separate installation.github.com · 2 Oct 2026
Trust anchor: The web visualization uses the root zone KSK as its default exclusive trust anchor, and users can configure arbitrary DNSKEY trust anchors in the options field.dnsviz.net · 2 Oct 2026
Security and compliance: The opened DNSViz pages describe DNSSEC analysis and verification features but make no security certification or compliance claim.dnsviz.net · 2 Oct 2026
Support: DNSViz invites comments and questions through its contact form; its contact page says Verisign Labs sponsors ongoing development.dnsviz.net · 2 Oct 2026
Intended users: The project describes DNSViz as a resource for understanding and troubleshooting DNSSEC deployment.dnsviz.net · 2 Oct 2026
Analysis: It visually analyzes a domain’s DNSSEC authentication chain and resolution path, and lists detected configuration errors.dnsviz.net · 3 Oct 2026
Open source: The DNSViz source repository identifies its license as GPL-2.0.github.com · 3 Oct 2026
Query sources: The probe command can query recursive DNS servers by default or authoritative DNS servers.github.com · 3 Oct 2026
Pre-deployment testing: DNSViz documents pre-deployment testing for zones and proposed delegation, glue, and DS record changes.github.com · 3 Oct 2026
Install platforms: The project documents packages for Debian, Ubuntu, Fedora, Gentoo, FreeBSD, RHEL and CentOS, plus Mac installation through Homebrew or MacPorts.github.com · 3 Oct 2026
Optional DNSSEC support: GOST DNSSEC algorithm and digest support requires the OpenSSL GOST Engine and M2Crypto.github.com · 3 Oct 2026
