 The platform network configuration can be updated using the `talosctl meta` command for the running node:
 
 ```bash
-talosctl meta write 0xa '{"externalIPs": ["1.2.3.4"]}'
-talosctl meta delete 0xa
+talosctl meta write 0x0a '{"externalIPs": ["1.2.3.4"]}'

 The initial platform network configuration for the `metal` platform can be also included into the generated Talos image:
 
 ```bash
-docker run --rm -i ghcr.io/siderolabs/imager:{{< release >}} iso --arch amd64 --tar-to-stdout --meta 0xa='{...}' | tar xz
-docker run --rm -i --privileged ghcr.io/siderolabs/imager:{{< release >}} image --platform metal --arch amd64 --tar-to-stdout --meta 0xa='{...}' | tar xz

 ```
 
 The platform network configuration gets merged with other sources of network configuration, the details can be found in the [network resources guide]({{< relref "../../../learn-more/networking-resources.md#configuration-merging" >}}).
