Assuming that none of the hosts has cached the entries, how many ARP broadcasts would be required for a host on one subnet to communicate with a host on a remote subnet that is separated by a single router?

203.200.5.0, 203.200.6.0, 203.200.7.0 and 203.200.8.0

You want to combine these addresses into one logical network to increase the host IDs that you can have on one subnet. Which subnet mask should you assign?

You have four Class C network addresses:

203.200.5.0, 203.200.6.0, 203.200.7.0 and 203.200.8.0
