FastDDNS

FastDDNS is a toolbox for IT technicians, network admins, CCTV installers, MSPs, and home-lab users. Manage changing IPs, configure cameras, and diagnose remote access on site. One toolbox combines DDNS, camera setup, ONVIF inspection, and internet-side checks. Why FastDDNS Plain DDNS updates a hostname. FastDDNS helps prove where a connection fails: on the device, at port forwarding, behind CGNAT, or at the ISP. DDNS hostname management • Create hostnames on FastDDNS domains or on your own domain. • See the current IP with country and ISP, last update time, expiry date, and service pack. • Copy hostname/IP, add notes, review history, and enable IP-change push notifications. • Ping a hostname, move it between service packs, or delete it. • DynDNS-compatible updates work with routers, NAS, scripts, and third-party clients. Auto Setup for CCTV Camera No more typing the DDNS server, hostname, username, and password into the camera's web UI. Enter a camera, DVR, or NVR IP on the LAN or WAN, port, and login. Tap Scan IP to pick the device straight from the LAN. Choose Hikvision, Dahua, EZVIZ, Imou, XMEye, HiLook, Tiandy, or Other. FastDDNS writes the DDNS settings and, where required, DNS or email settings. Manual DDNS Configuration covers Hikvision, Dahua, DrayTek, MikroTik, pfSense, Linux/curl, and Windows. ONVIF Camera Enter a camera IP to read manufacturer, model, firmware, serial number, hardware ID, hostname, service endpoint, ONVIF versions, and services without a password. Sign in with camera credentials to list every video stream and profile with snapshot thumbnails. Watch live video inside the app. Copy the RTSP link with or without credentials, ready for an NVR, VMS, or VLC. A tries-left counter helps avoid locking out the camera account. Network tools • LAN Scanner — Find LAN devices, identify vendors, and see open ports. • Port Checker — Test TCP/UDP ports from your phone and from the internet at once, so you know if the problem is forwarding, CGNAT, or the ISP. • Ping — Measure live latency, min/avg/max, packet loss, and standard deviation. • Traceroute — See each hop and transit delay. • CGNAT Checker — Detect ISP CGNAT and NAT loopback support. • MAC Vendor Lookup — Identify a manufacturer from a MAC address. • DNS Lookup — Query A, AAAA, CNAME, MX, TXT, and NS records. • MX Lookup — Find mail server records for a domain. • Domain Whois Lookup — View domain registration and owner details. • IP Whois Lookup — Identify the organization behind a public IP. • Storage Calculator — Estimate CCTV storage from channels, bitrate, resolution, and schedule. Compatible devices and systems Dahua, Hikvision, Imou, EZVIZ, HiLook, XMEye, Tiandy, UNV, MikroTik, pfSense, DrayTek, Windows, Linux, NAS, and DynDNS-compatible clients. Who it's for • IT technicians and network administrators • CCTV and IP-camera installers • MSP field technicians • Home-lab and self-hosting users Plans • Free 1 Hostname — one hostname, valid for one year, free. • Free with Limited Use — extra hostnames, 30 days each; reactivate to continue. • Premium Packs — more hostnames and longer validity.
