Design: to apply for A business into A class C IP address, but due to business requirements, internal must have four independent network, for the accounting office, workshop, sales workshop with use of administrative office in A factory, site used no more than 30 units, each department please use the concept of subnet division, completed the design, the address is as follows:
IP address: 11001011, 01001010, 11001101, 00000000

CodePudding user response:

No more than 30 Taiwan, that is, up to 30 IP, plus host and 0 1 two IP addresses, 30 32=^ 2 + 2=5, then at least five host addresses per subnet bits, the network is given 203.74.205.00000000, behind the last byte partition off after five and then there were three, four network will need to 2 subnets, take 203.74.205.0 00 00000203.74. 205.0 01 00000203.74. 205.0 to 10 00000203.74. 11, 00000, 205.0, however, if you want to rigorous, each network if need each other, then divide must be set aside at least one subnet gateway address, 30 + 1 + 2=33 <=64=2 ^ 6, at this time requires six host, subnetting should be followed: 203.74.205.00 000000203.74. 205.01 000000203.74. 205.10 000000203.74. 205.11, 000000,

Very thank you oh

You're welcome, learn how to points, not learn to find a few problems more practise, subnetting is based, is very important,

Learned I only make 5 host, did not think of six host, thank you
