我是网络程序员而且我不熟悉网络,我有下一个问题我在互联网上搜索了很多文章,但它没有帮助,我发现了解子网划分的困难..我讲道任何可以帮助我解决这个问题的人:)
问题是:
您已分配B类网络地址:165.10.0.0/16
Departments Number of employees D1 800 D2 200 D3 50 D4 1600 D5 210 D6 60 D7 60 D8 36 D9 210
如何使用FLSM方法在部门上分发此地址?

• Max host in D4 which is 1600 and will take it to calculate subnet
• Address Size : 2^11-2=2046
• Subnet Mask : 255.255.248.0
• To calculate new subnet mask: 256 - 248 = 8
• 8 between networks and each one has 2046 addresses.
Dep Number of Employees Address Size Subnet Address
Subnet Mask Start - End IP Broadcast Address
D4 1600 2046 165.10.0.0/21 255.255.248.0 165.10.0.1 - 165.10.0.254 165.10.0.255
D1 800 2046 165.10.8.0/21
255.255.248.0 165.10.8.1 - 165.10.8.254 165.10.8.255
D5 210 2046 165.10.16.0/21
255.255.248.0 165.10.16.1 - 165.10.16.254 165.10.16.255
D9 210 2046 165.10.24.0/21
255.255.248.0 165.10.24.1 - 165.10.24.254 165.10.24.255
D2 200 2046 165.10.32.0/21
255.255.248.0 165.10.32.1 - 165.10.32.254 165.10.32.255
D6 60 2046 165.10.40.0/21
255.255.248.0 165.10.40.1 - 165.10.40.254 165.10.40.255
D7 60 2046 165.10.48.0/21
255.255.248.0 165.10.48.1 - 165.10.48.254 165.10.48.255
D3 50 2046 165.10.56.0/21
255.255.248.0 165.10.56.1 - 165.10.56.254 165.10.56.255
D8 36 2046 165.10.64.0/21
255.255.248.0 165.10.64.1 - 165.10.64.254 165.10.64.255
对于无格式的格式化文本,我无法在此处粘贴表格。

主机位为11 ...表示每个n / w将有2 ^ 11个主机 N / W位将是21 ...意味着将有(16-11)即5 ..即2 ^ 5 n / w即32 n / w SM = 255.255.248.0
