1) Planning and use of IP address of Xishan No.1 apartment A (student 1 1C apartment)
The network center will assign 8 continuous class C IP addresses to each dormitory building in the whole school; Each floor has a class C address (254 IP addresses available continuously), and each dormitory is pre-allocated with 5 IP addresses. The masks in student dormitories are unified as: 255.255.255.0.
At present, the student apartment 1 1C has been connected to the campus network 1000Mbps optical fiber backbone network, and its network IP address is172.173.0 ...172.438+0./kloc.

Each dormitory has five consecutive IP addresses, and the initial IP is selected as follows: based on the network IP of the floor where the dormitory is located, add (the room number where the dormitory is located ×5) in the fourth paragraph.
For example, the IP address selection method of Room 308 in student apartment 1 1C is as follows: check the 3rd floor network of apartment 1 175.0 to initiate IP; Then add (08×5=40) to the fourth paragraph 0 of172.21.175.0, and it becomes172.21.175.40. Therefore, the IP address of student 1 1C apartment 308 ranges from172.21.175.40 to 172.438+0. 175.44.
2) The IP address of Xishan Apartment B (student apartment11b) is planned and used.
The network center will assign 8 continuous class C IP addresses to each dormitory building in the whole school; Each floor has a class C address (254 IP addresses available continuously), and each dormitory is pre-allocated with 5 IP addresses. The masks in student dormitories are unified as: 255.255.255.0.
At present, the student apartment 1 1B has been connected to the campus network 1000Mbps optical fiber backbone network, and its network IP address is172.21...172+0.
