Here is an example of the interfaces file for one bridge:
iface lo inet loopback
iface br0 inet static
now, let's say the IP of my machine is 18.104.22.168, how do change the file? why at every example I see the same 192.168.0.1 address? I'm sorry if this too stupid, but well, I'm a newbie in this networks things. Have always used dhcp and never cared about IP addresses.
After that, how do I configure three IPs ?
