# Network Controller ![Network Controller](/files/xNWj4mnREAKkxeiDCq0O) The Network Controller is the brain of any Network. A Network cannot function without a controller nor can it have more than one. So long as a Network block is connected to the Controller via any series of other [Network Nodes](/networks/network-nodes.md) it will become a child node of the Controller. You can use a [Network Probe](/networks/tools/network-probe.md) on a Controller to see exactly what nodes are connected to the Controller, how many of those nodes you have and the total volume of items stored with in the Network as a whole --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.sefiraat.dev/networks/network-nodes/network-controller.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
