<![CDATA[PT Transformasi Data Digital (HostData) operates as a web hosting and domain service provider in Indonesia, facing recurring challenges related to DNS propagation. Clients often encounter issues accessing their newly acquired domains or updated DNS records due to a lack of understanding of the propagation process. In response, HostData has developed a DNS Propagation checking system to streamline verification for clients and its support team. This system allows clients to monitor DNS propagation independently, acknowledging variations based on their Internet Service Provider (ISP). Leveraging six local ISPs—Telkomsel, Indosat, XL, Three, Smartfren, and Indihome—the system utilizes repurposed Set Top Boxes (STBs) as mini servers for real-time DNS value verification. These STBs connect via Zerotier to a Virtual Private Server (VPS) with a public IP address, serving as the central control unit. This innovative solution enables clients to confirm domain resolution and serves as an educational tool, offering insights into DNS propagation mechanics.]]>
