IP addressing error with docker with docker-compose

Question

I have mounted two identical docker on two ubuntu vps with docker-compose. The concern is that the first one works well, and the pilces dialogue between it, the second one not. What I see is that the ip set by default in 1 / is 172.XXX and the one set in 2 / is 192.XXX I am on virgin vps, no particular configuration file ... but I do not see how this is possible. Here is the docker-compose

version: '2.4'
services:
  redis:
    image: redis:alpine



 db:
    image: mariadb:10.5
    working_dir: /application
    command: [mysqld, --character-set-server=utf8mb4, --collation-server=utf8mb4_unicode_ci, --innodb-file-format=Barracuda, --innodb-large-prefix=1, --innodb-file-per-table=1]
    volumes:
      - pimcore-demo-database:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=ROOT
      - MYSQL_DATABASE=pimcore
      - MYSQL_USER=pimcore
      - MYSQL_PASSWORD=pimcore

  php:
    image: pimcore/pimcore:PHP8.0-apache
    volumes:
      - .:/var/www/html:cached
    ports:
     - 80:80
     - 443:443
    environment:
     - APACHE_DOCUMENT_ROOT=/var/www/html/public

  php-debug:

    volumes:
      - .:/var/www/html:cached
    ports:
     - 88:80
    environment:
      - PHP_IDE_CONFIG="serverName=localhost"
      - APACHE_DOCUMENT_ROOT=/var/www/html/public

Try to add networking config inside your compose yml to use specific IPs, like following:
