In order to configure Docker to use a certain network range just paste this into your /etc/docker/daemon.json.

{
  "default-address-pools": [{ "base": "192.168.199.0/24", "size": 28 }]
}

It configures Docker to use the address space from 192.168.199.0 to 192.168.199.255 in blocks of 16 addresses each. This means the docker0 network gets created like this:

# ip a
64: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default
    link/ether 02:42:2c:a9:5e:96 brd ff:ff:ff:ff:ff:ff
    inet 192.168.199.1/28 brd 192.168.199.15 scope global docker0
       valid_lft forever preferred_lft forever

and all other bridge networks in the same way:

# ip a
65: br-fc09df0ee651: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default
    link/ether 02:42:3d:0c:57:b3 brd ff:ff:ff:ff:ff:ff
    inet 192.168.199.17/28 brd 192.168.199.31 scope global br-fc09df0ee651
       valid_lft forever preferred_lft forever

Here you have the CIDR notation for reference.
