New Features


A mozilla-based DNSSEC-enabled browser with DANE support - Added support for validation of SSL certificates using the DANE protocol.

The Owl sensors perform periodic DNS queries and report to the Owl manager the time taken for each query. Over time, this shows the responsiveness of the DNS infrastructure.


Added support for validation of SSL certificates using the DANE protocol.


A patch to support DNSSEC checks in Qt5 DNS lookups


Many new features have been added: - The validation tree now supports clicking on boxes to highlight it and the arrows that derive from it. Great for use when teaching about DNSSEC. - An extensive filter/effect editor now lets you tailor the look of a graph to color-code, set the alpha levels, etc of nodes based on their names, status, data types, etc. - Right clicking on a node lets you center the graph on that node. - More data types are collected and shown in the data view. - Support for arguments on the command line for parsing log files, pcap files and domain names. - The validation view has received a visual clean-up - Many other bug fixes
