How to put these IP addresses into a network segment

I'll come to your questions.

First of all, an answer can be drawn that your question is wrong.

192.*.It is a Class C IP address, and the maximum mask can only be so you can't put this in the same network segment, if you want to put it in the same network segment, you can only change the Class C IP address to Class B or Class A.

The mask of a Class A IP address can be:

The mask of a Class B IP address can be.

The mask of a Class C IP address can be.

Let's say you have a class A.

It can be set to mask in the same network segment.

It can be set to mask in the same network segment.

It can be set to mask in the same network segment.

Class B. - Can be set in the same network segment mask - Can be set in the same network segment mask.

Class C. It can be set to mask in the same network segment.

How to communicate IP addresses between different CIDR blocks:

The first method is to change the subnet mask to the same network segment.

The CIDR blocks of two different subnets cannot reach each other, and after changing the original subnet mask to the subnet mask, both are in the same network segment, and they can access each other.

The second method requires a Layer 3 switch or router.

The device in the left subnet uses the interface IP of the router connected to as the gateway, and the device in the right subnet uses the interface IP of the router as the gateway, and the two subnets can communicate.

Communication principle: There are direct routes to two subnets on the router, and when the subnet device uses the router as the gateway, it can directly access the target according to the direct route, and the router is the gateway when the target is returned, and the direct route is also directly called to return the information.

The third method: there are multiple isolation devices in between.

The two adjacent subnets use the adjacent router interfaces as gateways, and the two routers write static routes to each other's subnets. Alternatively, two routers can run the dynamic routing protocol and advertise the routes of the subnets where they are located.

This is a general, three-layer communication environment, which is no different from communication on the Internet.

The public address is the responsibility of the Inter NIC (Internet Network Information Center). These IP addresses are assigned to organizations that register and apply to Inter NIC. Direct access to the Internet through it.

2. Private address.

A private address is a non-registered address that is intended for internal use within an organization.

Class A, Class B, Class C.

First of all, from the "few digits" of the IP, you can see which type of IP address the IP address belongs to, such as A, B, C (these three types are mainly used on the network); Secondly, you can also get the network address mask of the address from the IP address.

2.Using NAT technology, computers can share a network IP address for two days, and if a router is used in the dormitory, the entire dormitory can also share an IP address.

The address will of course change (not absolutely). In the case of laptops, it is basically the same when using wireless Internet access and using a network cable to access the Internet. In addition, the IP address of different carriers (China Telecom, Netcom) will not be the same.

In addition, the IP address can also be manually changed (but the manually modified IP address may not be able to access the Internet, unless the IP address is given to you by the carrier).

4.IP is the IP you want to access another IP through one IP, which is actually your indirect access. But as long as you are connected to the Internet, your IP address is unique on the network (but if you are in a LAN with NAT, there may be several stations with the same network IP address, but your LAN address is still different).

Dynamic IP addresses are random IP addresses that are assigned when needed. Dynamic IP address and static IP address are corresponding, the so-called dynamic means that every time you go online, Telecom will randomly assign an IP address, static refers to the fixed allocation of an IP address, every time you use this address. Because IP address resources are very valuable, the IP addresses used by most users when surfing the Internet are dynamic, just like computers that access the Internet through modem, isdn, adsl, wired broadband, cell broadband, etc., are temporarily randomly assigned an IP address every time they go online.

An IP address is a 32-bit binary number of addresses, and theoretically, there are about 4 billion (2 to the 32nd power) possible address combinations, which seems like a large address space. Actually, according to....

Use a Layer 3 switch to configure different VLAN gateways on the Layer 3 switch.

In Chinese, the word "network" was first used in the Dictionary of Modern Chinese

1993 edition) makes this explanation: "In an electrical system, a circuit composed of several elements used to transmit electrical signals according to certain requirements or a part of such a circuit is called a network. ”

Mathematically, a network is a type of graph, and it is generally considered to refer specifically to a weighted graph. In addition to the mathematical definition, a network has a specific physical meaning, that is, a network is a model abstracted from some kind of practical problem of the same type.

In the field of computer, the network is a virtual platform for information transmission, reception and sharing, through which the information of various points, surfaces and bodies is linked together, so as to realize the sharing of these resources. The Internet is the most important invention in the history of human development, which has improved the development of science and technology and human society.

Class A IP addresses range to. There are 126 Class A networks available, each capable of accommodating more than 100 million hosts.

Class B IP address address range. There are 16,382 Class B networks available, each capable of accommodating more than 60,000 hosts.

There are more than 2.09 million Class C IP addresses ranging from Class C to Class Networks, and each network can accommodate 254 hosts.
