DNSviz, a new tool from Sandia National Laboratories, aims to help users visualize the status of a DNS zone, showing DNSSEC authentication chain for a particular domain name and its resolution path in the DNS namespace. Designed as an aid in understanding and solving problems in DNSSEC deployment, the tool also lists configuration errors it detects.  (Above, part of the analysis for dnssec-deployment.org.)  Feedback is encouraged for the new tool.
