Hello @ImChiip This isn't a default from Portainer, this is how Docker uses the bridge network. If you wish you can define your own custom bridge network. You can do this via the Network page you are in.

Or create a stack with a network with something like

networks:
  custom_net:
    driver: bridge
    ipam:
      config:
        - subnet: 192.168.100.0/24

As mentioned above, this is not a Portainer related setting and is how Docker works by default.
