This article is about what ip addresses represent from left to right on your computer. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The ip address represents the network address and host address from left to right, respectively. Class An IP address consists of 1 byte network address and 3 byte host address; Class B IP address consists of 2 byte network address and 2 byte host address; Class C IP address consists of 3 byte network address and 1 byte host address.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

The IP address consists of two parts, one is the network address and the other is the host address.

1. A class An IP address consists of a 1-byte network address and a 3-byte host address, and the highest bit of the network address must be "0".

2. The class B IP address consists of a 2-byte network address and a 2-byte host address, and the highest bit of the network address must be "10".

3. The class C IP address consists of a 3-byte network address and a 1-byte host address, and the highest bit of the network address must be "110".

For example, in a network segment such as 192.168.0.0, the network number is 192.168.0.0 and the broadcast address is 192.168.0.255.

Therefore, in a local area network, there are two fewer addresses that can be configured in the computer than in the network segment (network number, broadcast address). These addresses are called host addresses.

In the above example, only 192.168.0.1 to 192.168.0.254 host addresses can be configured on the computer.

IP address Mask:

To identify the network and host parts of the IP address, it is combined with the address mask (Address Mask), which, like the IP address, is 32 bits, represented in dotted decimal. The mask part of the network part of the IP address is all "1", and the mask of the host part is all "0".

By default, if there is no subnetting, the subnet mask of the Class A network is 255.0.0.0, the subnet mask of the Class B network is 255.255.0.0, and the subnet mask of the Class C network is 255.255.255.0. Using subnets, the use of network addresses will be more efficient.

With the subnet mask, the IP address is identified as follows:

Example: 192.168.1.1 255.255.255.0 or marked as 192.168.1.1ax 24 (the number of "1s" in the mask)

Fixed IP and dynamic IP

Basically, these two things are the result of the growth of a large number of Internet companies. for example, if you apply to China Telecom for a commercial ADSL line, he will give a fixed entity IP, which is called "fixed IP".

If you apply for a timed ADSL, the IP may be shared by dozens of people, so every time you reboot to the Internet, the IP of the computer will not be fixed, so it is called "dynamic IP" or "floating IP".

Basically, both of them are "entity IP", but Internet companies use different methods to assign them to users, resulting in different names.
