While setting up PCF in my home lab I noticed a quirk. You have to create a network to be used and specify a subnet for PCF to assign IPs from. Personally I would rather specify a range rather than a whole subnet. As a result you have to exclude out ranges that might be used by other VMs/Systems/Devices on your network. I did so for different subnets and stopped at .254 knowing that .255 is the broadcast address for that subnet. Whooops I think I found a bug, because any other software would know not to use the broadcast address. Time to ping my mates at Pivotal.
