FastDDNS

FastDDNS is a free Dynamic DNS (DDNS) service with built-in network tools for remote access, device setup, and troubleshooting.

Create DDNS hostnames, track IP changes, and diagnose connection problems from one mobile app. FastDDNS is especially useful for CCTV installers, IT technicians, home lab users, and anyone managing devices behind a changing public IP.

Why FastDDNS

Most DDNS apps stop at hostname management. FastDDNS also includes a LAN scanner, ping with live graphs, DNS and Whois lookups, a CGNAT checker, and a CCTV storage calculator — tools commonly used during on-site setup and troubleshooting.

It also provides setup references for common devices and systems, including Dahua, Hikvision, MikroTik, pfSense, DrayTek, Windows clients, and Linux-based environments.

• Create and manage DDNS hostnames
• View current IP, last update time, expiry date, and service pack details
• Review recent IP update history
• Check CGNAT when remote access is not working
• Turn on IP change notifications
• Add notes to each hostname for easier organization
• Move hostnames between service packs
