Obtaining a list of active nodes that use VoIP (Voice over Internet Protocol) can be effectively done through a repeater directory. A repeater directory provides a comprehensive listing of amateur radio repeaters, including those that are part of various digital communication systems such as VoIP. These directories are typically maintained by organizations or clubs and can include additional details such as the frequencies, location, and operational guidelines of the nodes.

While online forums and local clubs may have discussions or information related to VoIP nodes, they may not always be comprehensive or up-to-date. A government database is unlikely to provide such specific information on amateur radio operations, as VOIP and repeaters are generally the domain of amateur radio organizations rather than government oversight. Therefore, when searching for a structured and accurate source of active VoIP nodes, referring to a repeater directory is the most reliable approach.
