Need a script to get hosts where observed IP-Range

For a customer I need to filter which Hosts (and VM's) have a connection with the DMZ VLAN's.

Problem is, the physical and virtual network VLAN's over multiple vCenter's aren't cosistent. So it can occur physical VLAN 24 is presented in the virtual network as VLAN 24 in one cluster and VLAN356 in an other.

My idea is to create a script that will search for observed IP-ranges (like 192.168.128.xxx) and show the VLAN Name, VLANID and VMHost information.

I'd like to get a csv file with this information, to be able to sort the outcome.

I really don't see if/how this can be done, and so I ask the help of the GURU's

Thanks in advance!
