• Full DNS record management (A, AAAA, PTR, and TXT records)
• IPv6 prefix tracking and updates
• Support for zone apex (root domain) updates
• FreeIPA API integration

Bash Script Features

• Dual authentication support (FreeIPA user/password or TSIG keys)
• Flexible configuration with environment variables and multiple .env file locations
• Advanced operational modes (debug, dry-run, auto-update)
• Multiple IP provider fallback for reliable address detection
• Automatic updates with version checking

Mikrotik Script Features

• Native RouterOS integration
• DHCP client-based IP detection
• DoH (DNS over HTTPS) support for TXT record queries
• Cookie-based FreeIPA authentication

Prerequisites

For Bash Script

• curl
• jq
• dig
• nsupdate
• ipcalc or ipcalc-ng ("ng" for Debian-based distros)

For Mikrotik Script

• RouterOS with SSH capability
• DHCP client configuration
• Internet connectivity for API access

Configuration

Bash Script Configuration

The script looks for a .env file in the following locations (in order):

1. Current working directory (.env)
2. Script's real path directory (.env)
3. Script's real path directory (.env.<script_name>)
4. Script's symlink path directory (.env.<symlink_name>)
5. /opt/skyfritt-tools-env/.env.<symlink_name>

Required Variables

Variable	Description
SERVER	DNS server hostname or IP address
ZONE_NAME	DNS zone name (e.g., "example.com")
RECORD_NAME	Hostname to update (without domain). Skip to update zone apex

[Rest of the existing configuration documentation remains the same...]

Mikrotik Script Configuration

Configure the script by modifying the CONFIG dictionary:

:local CONFIG {
    "wanInterface"="VLAN666_Altibox";
    "IpaServer"="ipa.demo1.freeipa.org";
    "dnsZone"="demo1.freeipa.org";
    "IpaUser"="admin";
    "IpaPassword"="Secret123";
    "apiVersion"="2.253";
    "recordTTL"="300";
    # [Additional configuration options...]
}

Bash Script

# Basic usage
./dnsdrone.sh

# Debug mode
./dnsdrone.sh -d

# Dry run
./dnsdrone.sh -n

# Check for updates
