IPNotify

README

IPNotify

IPNotify is an open-source tool that monitors IPv4 address changes and sends email notifications in real-time. It's ideal for anyone who needs to stay informed about network changes and wants a simple, efficient way to receive alerts.

In addition to email notifications, IPNotify now also supports Dynamic DNS (DDNS) updates with DNSPod. DDNS allows you to automatically update DNS records for a given domain and subdomain, eliminating the need for manual updates when your IP address changes.
