DNS View Synchronization Tool

A Python script for bi-directional synchronization of DNS A records between two Infoblox Universal DDI views.

Overview

This tool synchronizes DNS A records between two views (e.g., AZURE-3 and AZURE-9) within the same DNS zone. It prevents sync loops and handles conflicts.

Note: This is a Minimum Viable Product (MVP). No support or warranty is provided.

Features

• Bi-directional sync between two DNS views
• Loop prevention using detailed comment markers
• Conflict detection and resolution
• logging with timestamps

Installation

# Clone the repository
cd infoblox-UDDI-zonesync

# Create and activate a virtualenv (recommended)
python3 -m venv .venv && source .venv/bin/activate

# Install dependencies
pip install --upgrade pip
pip install -r requirements.txt

Configuration

1. Copy the configuration template:

cp config.py.example config.py

2. Edit config.py with your settings:

# Infoblox API Configuration
INFOBLOX_API_URL = "https://csp.infoblox.com"
INFOBLOX_API_TOKEN = "your_api_token_here"

# DNS Views to synchronize
DNS_VIEW_SOURCE = "AZURE-3"
DNS_VIEW_TARGET = "AZURE-9"

# DNS Zone to synchronize (note the trailing dot)
DNS_ZONE_NAME = "privatelink.blob.core.windows.net."

Usage

Run synchronization:

python3 sync_dns_zones.py

Configuration Parameters

Setting	Description	Example
INFOBLOX_API_URL	API endpoint	https://csp.infoblox.com
INFOBLOX_API_TOKEN	API token with DNS permissions	your_token_here
DNS_VIEW_SOURCE	Source DNS view name	AZURE-3
DNS_VIEW_TARGET	Target DNS view name	AZURE-9
DNS_ZONE_NAME	Zone to sync (with trailing dot)	privatelink.blob.core.windows.net.

How It Works

1. Fetch Records: Retrieves A records from both views
2. Compare: Identifies differences between views
3. Sync: Creates missing records in each view
4. Loop Prevention: Uses detailed comment markers to prevent infinite loops

Sync Comments

Records include detailed metadata:

Synced from AZURE-3 on 2025-08-01 13:00:25 UTC, created: 2025-07-15T10:30:00Z

Example Output

2025-08-01 13:00:24,329 - INFO - Starting DNS Zone Synchronization
2025-08-01 13:00:24,329 - INFO - Views: AZURE-3 ↔ AZURE-9
2025-08-01 13:00:25,666 - INFO - Created 20vms01stor: 10.10.10.5
2025-08-01 13:00:27,854 - INFO - Records synced AZURE-3→AZURE-9: 3
2025-08-01 13:00:27,854 - INFO - Total records synced: 5

Automation

For regular synchronization, add to crontab:

# Run every 5 minutes
*/5 * * * * cd /path/to/dns-sync && python3 sync_dns_zones.py >> /var/log/dns-sync.log 2>&1

Troubleshooting

Configuration Not Found

• Copy config.py.example to config.py
• Update with your API token and view names

Authentication Failed

• Verify API token is valid and has DNS permissions

View Not Found

• Check view names are correct (case-sensitive)
• Verify views exist in Infoblox system

Zone Not Found

• Ensure zone name has trailing dot: example.com.
• Verify zone exists in both views

Requirements

• Python 3.7+
• requests library
• Valid Infoblox Universal DDI API access

Limitations

• Only synchronizes A records (IPv4)
• Does not delete records (create/update only)
• Manual conflict resolution required for simultaneous changes
• Single API token (both views must be accessible with same token)
