 This script is used to update Dynamic DNS (DDNS) service based on Cloudflare! Access your home network remotely via a custom domain name without a static IP! Written in pure BASH.
 
-## Support Me
+This version of this script allows you to update multiple domains/sub domains with the same public IP for IPv4, IPv6 version remains per single domain.
