###### Procedure

1. Sign in as root user

2. Open `/etc/default/grub` with nano, e.g.

    ```
    nano /etc/default/grub
    ```

3. Add `net.ifnames=0` to the `GRUB_CMDLINE_LINUX_DEFAULT` option, e.g.

    ```
    GRUB_CMDLINE_LINUX_DEFAULT="... net.ifnames=0"
    ```

    !!! warning "Caution"

        Be mindful of the existing options set for `GRUB_CMDLINE_LINUX_DEFAULT`. Append `net.ifnames=0` to the end of them if they exist. The `...` in the example above indicates an indeterminate amount of options irrelevant to the guide.

4. Save and run `update-grub && reboot`

5. Finally, run `ip address` to inspect network interfaces for names like `eth0` and `eth1`
