What is the beginning and ending IP addresses for the following subnets?

Recently I was asked to setup a network appliance that finds and monitors network connected print devices in big networks.  I asked the network administrator to give me a list of all the subnets that were active in his WAN.  He gave me back the following list:

I guese I don't know how to interpret this information, because looking at this, I cannot guese what the first and last IP addresses would be based on this notation type.

Can some one interpret this so that I would know what the IP address range would be here?

To be honest neither can I !
The idea behind subnet masks is this every binary digit from the right masks the ip address. This gives you a network address where you can send all the data for that network.
You network data does not conform to this idea.

Looks like the network administrator made a mistake and gave me the subnet masks in reverse.  I like the subnet calculator though - thank you both for your assistance.
he gave u wildcard mask, not subnet mask.
