Anonymous users2024-02-15In the four segments of an IP address, the first segment is the network number, and the remaining three segments are the local computer number. If binary is used.
If you want to represent an IP address, a Class A IP address is a 1-byte network address.
and a 3-byte host address, and the highest bit of the network address must be "0". The length of the network identity in a Class A IP address is 8 bits, and the length of the host ID is 24 bits.
A Class B IP address is one in which the first two segments of the four segments of the IP address are network numbers. If the IP address is represented in binary, the Class B IP address is composed of a 2-byte network address and a 2-byte host address, and the highest bit of the Hengyou network address must be "10". In a Class B IP address, the length of the network identity is 16 bits, and the length of the host ID is 16 bits.
A Class C IP address.
It means that among the four segments of the IP address, the first three segments of the number are the network number, and the remaining number is the number of the local computer. If the IP address is represented in binary, the IP address of the C command pin consists of a 3-byte network address and a 1-byte host address, and the highest bit of the network address must be "110". The length of the network ID in the Class C IP address is 24 bits, and the length of the host ID is 8 bits.
Class A IP addresses range from to (binary representation is: 00000001 00000000 00000000 00000001 - 01111111 11111111 11111111 11111110). The last one is the broadcast address.
Class B IP addresses range from (binary representation is: 10000000 00000000 00000000 00000000001-101111111 11111111 11111111 11111110). The last one is the broadcast address.
Class C IP addresses range from (binary representation is: 11000000 0000000 000000000 00000001 - 11011111 11111111 11111111 11111110). The last one is the broadcast address.
3. The subnet mask is different
The subnet mask of a Class A IP address is.
The subnet mask of a Class B IP address is.
The subnet mask of a Class C IP address is:
4. The scope of application is different
The applicable type of Class A is a large network, with a small number of Class A network addresses, with 126 networks, and the maximum number of hosts supported by each network is 256 to the 3rd power - 2 = 16777214;
The applicable type of Class B is a medium-sized network, with a moderate number of Class B network addresses, with 16,384 networks, and the maximum number of hosts supported by each network is 256 to the 2nd power - 2 = 65,534 hosts;
Class C is applicable to small networks, with a large number of Class C network addresses, with more than 2.09 million networks, suitable for small-scale local area networks, and the maximum number of hosts supported by each network is 256 to the power of 2 - 2 = 254.

Anonymous users2024-02-14The four digits of an IP address represent the network type, network range, network bits, and host bits. An IP address is made up of 32-bit binary digits, and every 8 bits represents a decimal number ranging from 0-255.
For example, binary is expressed as.
An IP address is composed of two parts: the network address and the host address. The network address can be used to identify the network on which the device is located, and the host address is located at the back end of the IP address to identify the device on the network.
1. Class A IP address.
A Class A IP address consists of a 1-byte network address and a 3-byte host address, the highest bit of the network address must be "0", and there are 126 Class A networks available, each of which can accommodate 1677214 hosts.
2. Class B IP address.
A Class B IP address consists of a 2-byte network address and a 2-byte host address, with the highest bit of the network address having to be "10".
3. Class C IP address.
A 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", and the Class C network can reach 2097152, and each network can accommodate 254 hosts.
The IP address is the code name of your computer network, just like your house number, each one is different from each one.
If the "Local Connection" display status changes to "Restricted or No Connection" for no reason, this is usually due to the fact that the NIC is not assigned a fixed IP address. Under normal circumstances, when we find that the display status of "Local Connection" is abnormal, we can often try to set a static IP address for the network connection first, which can often solve many inexplicable network failures for us. Once we find that the local network connection does not use a fixed IP address, we can click the "Start" "Settings" and "Network Connection" commands in turn, and then in the network connection list interface, right-click the "Local Connection" icon with the mouse, and execute the "Properties" command from the right-click menu to open the property setting window of the local connection; In the "General" tab page of the window, select the "Internet Protocol" item and click the "Properties" button once. >>>More

Macro substitution, which indicates the content in quotation marks, such as x="123"If you use x+100, you will get an error because you can't add the character type to the numeric type, and if you use &x+100, the result will be 223, and & will take out the 123 in x quotation marks as numeric data.
