Hi@akhtar,
You can reconfigure the default bridge network by providing the bip option along with the desired subnet in the daemon.json (default location at /etc/docker/daemon.json ) file as follows.
$ vim /etc/docker/daemon.json
{
"bip": "172.200.0.1/16"
}
Then restart the docker daemon as root.
$ systemctl restart docker
Hope this will help.
