-#### Configuring Address Manager
-
-The address manager receives observed addresses from network peers. We accept observed addresses once a certain number of peers have reported the same observed address within a certain window of time.
-
-```js
-const node = await Libp2p.create({
-  addressManager: {
-    observedAddresses: {
-      // we must receive the same observed address from this many
-      // peers before we start believe it
-      minConfidence: 4,
-      // an address must reach the minimum level of confidence within
-      // this timeout otherwise it will be ignored
-      maxLifetimeBeforeEviction: (60 * 10) * 1000 // ten minutes in ms
-    }
-  },
-  // ...other options
-})
-```
-
 #### Configuring Connection Manager
 
 The Connection Manager prunes Connections in libp2p whenever certain limits are exceeded. If Metrics are enabled, you can also configure the Connection Manager to monitor the bandwidth of libp2p and prune connections as needed. You can read more about what Connection Manager does at [./CONNECTION_MANAGER.md](./CONNECTION_MANAGER.md). The configuration values below show the defaults for Connection Manager. See [./CONNECTION_MANAGER.md](./CONNECTION_MANAGER.md#options) for a full description of the parameters.
