-    <a href="#slow-localhost">**Q**</a>. I'm connecting to `localhost` and it takes me nearly 1 second to connect. How do I fix this?
-
-    **A**. The underlying MongoDB driver defaults to looking for IPv6 addresses, so the most likely cause is that your `localhost` DNS mapping isn't configured to handle IPv6. Use `127.0.0.1` instead of `localhost` or use the `family` option as shown in the [connection docs](https://mongoosejs.com/docs/connections.html#options).
-
-    ```javascript
-    // One alternative is to bypass 'localhost'
-    mongoose.connect('mongodb://127.0.0.1:27017/test');
-    // Another option is to specify the `family` option, which tells the
-    // MongoDB driver to only look for IPv4 addresses rather than IPv6 first.
