CLI tool for searching PowerDNS zone listings

PDNS Zone Search

A lightweight CLI tool for searching PowerDNS zone listings and extracting matching record sets as structured JSON.

Overview

PDNS Zone Search is designed to simplify searching through PowerDNS zone files by providing a simple command-line interface to extract and filter DNS records. It takes the output from pdnsutil list-zone commands, parses it into structured data, and allows filtering by record name, type, and optionally by record data.

Installation

pip install pdns-zone-search

Usage

The tool is designed to be used in a pipeline with pdnsutil, reading zone data from standard input:

pdnsutil list-zone example.com | pdns-zone-search example.com A

Command Line Options

pdns-zone-search NAME TYPE

• NAME: The DNS record name to search for
• TYPE: The DNS record type (supported types: A, PTR)

Examples

1. Find all the A records for "www.example.com":

   pdnsutil list-zone example.com | pdns-zone-search www.example.com A
   

2. Find all the PTR records for "server.example.com" (searches the data field of the zone):

   pdnsutil list-zone 1.168.192.in-addr.arpa | pdns-zone-search server.example.com PTR
   

Output Format

The tool outputs JSON-formatted data for easy parsing in scripts:

[
  [
    "proxmox.demo.example.com",
    "3600",
    "IN",
    "A",
    "10.0.0.100"
  ],
  [
    "proxmox.demo.example.com",
    "3600",
    "IN",
    "A",
    "10.0.0.100"
  ],
  [
    "proxmox.demo.example.com",
    "3600",
    "IN",
    "A",
    "10.0.0.107"
  ]
]

For record sets with multiple entries (like multiple A records for load balancing), all matching records are returned in the array.

Features

• Parses the output of pdnsutil list-zone into structured data
• Filters records by name
• Returns full record sets (all records of the same name and type)
• JSON output for easy integration with other tools and scripts

How It Works

1. The tool reads zone data from standard input
2. It parses the zone data into a structured format
3. It filters records based on the provided name and type
4. It returns the matching record set as JSON
