🌐 DYNDNS - Dynamic DNS Updates

The dynamic-dns.js script allows you to automatically update DNS records when your public IP changes.

⚙️ Configuration

Run the script with no parameters to select which records to update:

./dynamic-dns.js

You'll be prompted with a simple menu to choose the records (only A or AAAA types are supported):

📋 Main Menu

1) List domains to select record for DYNDNS
2) DYNDNS list
b) Exit

🌍 Domain Selection

1) domain.com
2) xyz.tld
3) example.tld
b) Back

📡 DYNDNS List

1) xyz.domain.tld [A]
    ↳ Current IP: xxx.xxx.xxx.xxx
    ↳ TTL: 900
    ↳ Last checked: 2025. 04. 23. 19:19:06
    ↳ Last updated: 2025. 04. 23. 19:23:10

b) Back
d) Delete an entry
t) Set TTL for an entry

🕒 Cron Mode

Once you've selected your records, run the script in cron mode:

./dynamic-dns.js --cron

This will fetch your public IP from https://api.ipify.org and update the chosen records. It's recommended to schedule this via cron (e.g., every 5 minutes).
