Examples
virsh # net-info default
Name            default
UUID            1c42888c-82c9-4dda-bc9c-4387962a0c0e
Active:         yes
Persistent:     yes
Autostart:      yes
Bridge: virbr0
Displays basic information for the virtual network named "default".
If the host server is running Linux, then the Bridge field gives the name of the Linux network bridge being for the virtual network. 
virsh # net-info --network default
Name            default
UUID            1c42888c-82c9-4dda-bc9c-4387962a0c0e
Active:         yes
Persistent:     yes
Autostart:      yes
Bridge:         virbr0
Same as the above example.
Example in context
We begin with an existing virtual network, running on the host: 
virsh # net-list --all
Name                 State      Autostart
-----------------------------------------
default              active     yes
The virtual network "default" is active and enabled for automatic starting.
We use the net-info command to display further details: 
# net-info default
Name            default
UUID            1c42888c-82c9-4dda-bc9c-4387962a0c0e
Active:         yes
Persistent:     yes
Autostart:      yes
Bridge:         virbr0
Some of the same information can also be retrieved using the net-dumpxml command, then looking through the output: 
virsh # net-dumpxml default
<network>
  <name>default</name>
  <uuid>1c42888c-82c9-4dda-bc9c-4387962a0c0e</uuid>
  <forward mode='nat'/>
  <bridge name='virbr0' stp='on' delay='0' />
  <ip address='192.168.122.1' netmask='255.255.255.0'>
    <dhcp>
      <range start='192.168.122.2' end='192.168.122.254' />
    </dhcp>
  </ip>
</network>
