An organization requires a range of IP addresses to assign one to each of its 1500 computers. The organization has approached on Internet Service Provider (ISP) for this task. The ISP uses CIDR and serves the requests from the available IP address space 202.61.0.0/17. The ISP wants to assign an address space to the organization which will minimize the number of routing entries in the ISP’s router using route aggregation. Which of the following address spaces are potential candidates from which the ISP can allot any one to the organization?I. 202.61.84.0/21II. 202.61.104.0/21III. 202.61.64.0/21IV. 202.61.144.0/21
