Suppose a subnet with prefix 128.119.40.128/26. Provide an example of one IP address (of the form xxx.xxx.xxx.xxx) which can be allocated to this network. Assume an ISP owns the block of addresses of the form 128.119.40.64/25. Assume it wished to create four subnets from this block, with each block having same number of IP addresses. State the network addresses (of form a.b.c.d/x) for four subnets?
