dnstrace

This tool performs a DNS resolution by tracing the delegation path from the root name servers, and by following the CNAME chain. Each query is reported with statistics about all delegated name servers.

Features

• Follow CNAMEs
• Query all name servers in parallel and report stats for each
• Report about non glued name server lookup time
• Enable DNSSEC query option to better emulate name server queries
• Compute the cold best path as if the resolver started with an empty cache to recurse queried name
