The normal methods for something that

- should run once
- as root
- after boot
- with a dependency on the network

would be:

- an init.d/ script with a dependency on network
- a systemd unit with a dependency on network
- an /etc/network/interfaces.d/ script run every time a
  particular interface is brought up (i.e. post-up).
