السلام عليكم :

اتمني مساعدتي في حل الاسئلة التالية في اقرب وقت ممكن ..........بحثت كثير بس بدون جدوى ...........:cdcd::cdcd::cdcd::cdcd::cdcd::cdcdداير راسي قريب انتحر )

1-To which class do the following IP addresses belong? For each, write the resulting network mask.
(1) 10.0.0.1
(2) 192.168.0.1
(3) 172.16.0.1
(4) 210.83.24.45
(5) 224.0.0.1


2-Give a subnet address, in both CIDR prefix and network mask notation, of any subnet that contains 20 hosts with minimal wastage.

4. A company has X hosts in its network. Assume it needs only one classful network allocation. What class of address (A, B or C) would be needed to satisfy their needs? How many addresses would be wasted? Solve for the following values of X:
(1) 30
(2) 500
(3) 1000
(4)50000


4- Create at least three subnets out of the network 210.80.29.0/24. How many subnets did you create? How many hosts can each subnet contain? What are the addresses in each subnet, expressed in CIDR and with network mask, and the first and the last IP addresses.
