Get-AzureDnsZoneReport

<#
.SYNOPSIS
    Exports all DNS record sets from every Azure DNS zone.

.DESCRIPTION
    Walks every DNS zone in the subscription and exports its record sets
    to a single CSV, giving you an offline, reviewable reference of the
    tenant's actual DNS configuration instead of relying on memory or
    outdated documentation.

.PARAMETER ExportPath
    Path to write the CSV to. Defaults to the current directory.

.EXAMPLE
    .\Get-AzureDnsZoneReport.ps1

.NOTES
    Requires the Az.Dns module and an active Connect-AzAccount session.
