Il est possible d'explicite la conf dans Docker-compose 

<code yaml>
networks:
  backend:
</code>

<code yaml>
networks:
  backend:
    ipam:
      driver: default
      config:
        - subnet: 192.168.10.0/24
</code>

== network host

Il est possible de faire :
<code yaml>
networks:
  hostnw:
    external:
      name: host
</code>

Mais il est mieux de faire 

<code yaml>
services:
  webapp:
    build: .
    network_mode: "host"
