The record

Purpose: DNSViz visualizes DNS zone status to help understand and troubleshoot DNSSEC deployment, showing the DNSSEC authentication chain, resolution path, and detected configuration errors.
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.
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.
Validation status: The graph classifies DNS data as secure, bogus, or insecure based on whether a chain of trust exists from a trust anchor.
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.
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.
Output formats: The graph command can produce an image, a DOT graph, or an HTML file from serialized query results.
Container: A Docker container is available, and the project documents running DNSViz commands inside it.
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.
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.
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.
Security and compliance: The opened DNSViz pages describe DNSSEC analysis and verification features but make no security certification or compliance claim.
Support: DNSViz invites comments and questions through its contact form; its contact page says Verisign Labs sponsors ongoing development.
Intended users: The project describes DNSViz as a resource for understanding and troubleshooting DNSSEC deployment.
