 Until [node incentivisation](/learn/research#prevention-of-denial-of-service-dos-and-node-incentivisation) is in place, you should [operate extra nodes](/#run-a-waku-node) alongside the ones provided by the Waku Network. When running a node, we recommend using the [DNS Discovery and Static Peers](#configure-dns-discovery-and-static-peers) configuration to connect to both the Waku Network and your node.

+## Retrieving connected peers
+
+You can retrieve the array of peers connected to a node using the `libp2p.getPeers()` function within the `@waku/sdk` package:
+
+```js
+import { createLightNode, waitForRemotePeer } from "@waku/sdk";
+
+const node = await createLightNode({ defaultBootstrap: true });
+await waitForRemotePeer(node);
+
+// Retrieve array of peers connected to the node
+console.log(node.libp2p.getPeers());
+```
