VSOFT DDNS keeps your ERP, CCTV and remote systems online — even when your public IP changes. We monitor your IP automatically, update your DNS instantly, and configure port forwarding for you.
没有固定 IP 也能稳定对外访问 — 自动侦测公网 IP 变化、即时更新 DNS、协助 port forwarding 配置。
A Dynamic DNS service maps a fixed, easy-to-remember domain name to your ever-changing public IP address. When your ISP changes your IP, our system detects it and updates the DNS record automatically — so your domain always points to the right place.
动态 DNS（DDNS）让一个固定、好记的域名永远指向你不断变化的公网 IP。当 ISP 更换你的 IP 时，系统会自动侦测并更新 DNS 记录，确保域名永远连得上。
Perfect for ERP / AutoCount, CCTV, remote desktop and IoT systems that need stable external access.

Quick answers about our DDNS service
No. DDNS is designed exactly for connections with a dynamic (changing) public IP. We map a fixed domain to your IP and update it automatically whenever it changes. 不需要固定 IP — DDNS 就是为动态 IP 设计的。
Our monitoring detects IP changes quickly and pushes the new record automatically, minimizing any disconnection window. Actual propagation depends on the DNS TTL we configure for you.
Yes. We configure the relevant ports (e.g. 554/8000+ for CCTV, 1433 for SQL Server, 3389 for remote desktop) so multiple services run through the same domain securely.
We apply security hardening — restricting access, using HTTPS where possible, and recommending VPN or IP whitelisting for sensitive services — so only authorized traffic gets through.
Yes. We support clients across Malaysia. Most DDNS setup and monitoring is done remotely, with on-site visits arranged when needed.
