ZDNS is a high-speed DNS resolver and command line utility designed for large-scale DNS measurements.
It includes its own recursive resolution code and an optimized cache for performing lookups across diverse sets of names. The software can be used from the command line or as a resolver library, with modules that define how DNS queries are made and how responses are returned.
This is free and open source software.
Key Features
- Performs high-speed DNS lookups for large-scale measurement tasks.
- Provides both a command line tool and a recursive resolver library.
- Supports raw DNS modules for many DNS record types with JSON output.
- Includes lookup modules such as alookup, mxlookup, and nslookup for multi-step DNS queries.
- Offers local recursive resolution using the –iterative flag.
- Accepts input from stdin, files, zone files, and per-domain name server mappings.
- Supports configurable concurrency with thread and process controls.
- Includes output verbosity levels ranging from short results to full trace output.
