It is a problem that becomes familiar and is deep. TCP/IP

Sleep today's problem of delivering a basic problem of TCP/IP is a problem of Internet Protocol address.
If the person has challenged CCNA etc. , I think that it is a simple problem very much.

Then, today's material is [kochira] ↓↓.



- Internet Protocol address (IPv4)



Internet Protocol address composed of the binary number in 32 bits divides into the network part and the host part, the network part is used to distinguish and to identify the belonging network, and the host part is used to identify the computer in the belonging network etc.

These sentences are correct.
- The computer in the network that * host part = belongs that distinguishes the network that network part = belongs and identifies it etc. are identified.



It usually delimits every eight bits, and each item is shown by the hexadecimal number, and Internet Protocol address ties at the period and writes between those.

These sentences are wrong.
- It is not a hexadecimal number and the decimal number of Internet Protocol address.



There are some classes in Internet Protocol address, and class B for a small-scale network is used for class C for a medium-scale network among these for the large scale network as for class A. Moreover, the number of bits of network parts is fixation regardless of the class.

These sentences are wrong.
- For large scale network ..class A.., and for ..class C.. small-scale network
- 【 number of bits of network parts 】 is different in each class (A=8 bit, B=16 bit, and C=24 bit).



How?It is already a level somehow like the quiz rather than the examination paper. Such a score source the service problem sleeps ..doing Get surely.. and, then, : settling down, reading the problem, and taking care not to hang to a trivial hanging around here today.
