Consider a subnet with prefix 128.119.40.128/26. Give an example of one IP address (of form xxx. xxx. xxx. xxx) that can be assigned to this network. Suppose an ISP owns the block of addresses of the form 128.119.40.64/25. Suppose it wants to create four subnets from this block, with each block having the same number of IP addresses. What are the prefixes (of form a. b. c. d/x) for the four subnets?
