dnstable implements an encoding format for passive DNS data. It consists of a C library, libdnstable, and several command line utilities for creating, querying, and merging dnstable data files.
For details about how dnstable entries are encoded in data files, see dnstable-encoding(5).
The command line dnstable utilities are:
Converts passive DNS data to dnstable format.
Prints dnstable format files in text or JSON.
Searches dnstable data files.
Merges multiple dnstable data files together.
The main interfaces provided by the dnstable library are:
Provides a consistent interface for iterating over the data entries returned by other interfaces.
Encapsulates the fields contained in individual data entries.
Encapsulates query parameters for searching a data source.
Reads dnstable data from an mtbl source.
Also provided is the low-level dnstable_merge_func(3), a libmtbl-compatible merge function.
