Key Points

It seems likely that Cloudflare's standard tools cannot directly identify unused DNS records over 12 months due to data retention limits.
Research suggests using Cloudflare's DNS analytics for recent data (up to 62 days for Enterprise) and Logpush for longer-term logging.
The evidence leans toward needing external log storage via Logpush for comprehensive 12-month analysis, if not already set up.

Direct Answer

Understanding Your Needs
You want to find DNS records not used in the last 12 months, and with 3500 entries, this is a significant task. Cloudflare offers tools, but there are limits based on your plan and setup.

This script installs OpenAlgo without using Snap, setting up a simple HTTP server (no Nginx). It includes security configurations, virtual environment setup, and systemd service creation.
