How to transfer ping to other servers to prevent hackers 10

With CDN, you can hide your IP.

The total server of the Internet is actually the root server.

When accessing **, it has to go through a conversion process from ** to IP, which is done by accessing DNS, that is, the name server. Since the development of the Internet began in the United States, the United States has always maintained control over Internet domain names and root servers. At the top of the multi-level servers that provide domain name resolution are 13 root servers, all of which are managed by ICANN.

One of them is the primary root server, located in Dulles, Virginia, USA, the remaining 12 are secondary root servers, 9 are placed in the United States, 2 in Europe are located in the United Kingdom and Sweden, and 1 in Asia is located in Japan. However, on July 1, 2005, the United States** announced that the U.S. Department of Commerce would retain control of 13 domain root servers indefinitely.

If the United States does not want people to access certain domain names, it can block these domain names and make their IP addresses unresolvable, then the ** that these domain names point to is equivalent to disappearing from the world of the Internet. For example, in April 2004, due to the ". .ly' domain name was paralyzed, causing Libya to disappear from the internet for 3 days.

In addition, with the privilege of domain name management, the United States can also monitor the network usage of other countries, for example, the United States can conduct traffic access statistics on a certain type of ** in a certain country, from which it can roughly analyze the distribution of popular ** in that country and the access preferences of netizens.

You're right, all the information is stored on the server. However, different information is stored on different servers, for example: the information is saved on the NetEase server, and the information is saved on the Sina server, assuming that the NetEase server is broken, then this ** will not be accessible, but it will not affect the access of this **.

There are countless servers on the Internet, and there are millions of servers on Google alone!

Broadly speaking, a server refers to a computer system in a network that can provide certain services to other machines (if a PC provides FTP services, it can also be called a server).

In a narrow sense, a server refers to some high-performance computers that can provide services through the network. Compared with ordinary PCs, the stability, security, performance and other aspects are higher, so the hardware such as CPU, chipset, memory, disk system, and network is different from ordinary PCs.

A server should be simply a computer that can be accessed by multiple users at the same time. At the simplest point, if you share the PC you have now with someone else so that others can access the resources on your computer, your PC will become a server.

A server is a server that is stored in an Internet data center. It is mainly used for publishing and applying in the Internet.

The server is generally hosted in the computer room, which has UPS (battery) and air conditioning.

Other characteristics of a server that are different from desktops.

The first is hot-swappable. Although the server has high requirements for stability, the hardware that is turned on all year round still cannot avoid damage. Replacing hardware by shutting down can be costly, so hot swapping is necessary.

All kinds of storage, boards, and even CPUs on the server can be replaced without shutting down.

The second is strong remote management capabilities. The server is generally in the computer room, far away from the technicians, and some are even in different cities, if there is a problem to the site and then solve it will undoubtedly waste a lot of time, so remote management and monitoring is essential. Generally speaking, today's commercial servers have an external embedded management system, which can remotely monitor the health status, configure BIOS, network, storage, reinstall the system, and so on.

Our latest HP server management system can remotely manage power, network, storage, servers, cabinets throughout the data center in batches, and for servers can be configured in batches with network, SAN, local RAID, BIOS, firmware, and even operating system and drivers.

The third is powerful parallel computing capabilities. Desktop computers can't handle dozens of high-load concurrent applications if they die, but servers need to process thousands of requests at the same time, so the concurrency capacity is much stronger than desktops. Desktop CPU quadruple cores and eight threads are overperformance for many people, but hundreds of threads on a server are not unusual.

Fourth, a lot of server software is not like a desktop that can be used by buying a key, but buying a license. Like Oracle's license, it is sold by CPU core, and one core costs hundreds of thousands.

Didn't understand what you meant. A server is a computer that you specify for the purpose of using it as a network service. Rather than saying that the server is a specialized computer.

Any computer can be used as a server, depending on what you think. Of course, the computer that is generally used as a server must have good stability, so you should buy the corresponding computer as a server according to what you want to do with it. If it's just a normal web service, it's an FTP service.

Then an ordinary computer is fine, if it is used for data storage, it must be advanced.

I'll give you a **, you go and see.

This is due to the fact that all IPv4 root servers are managed by ICANN, the Internet Assigned Names and Numbers Authority authorized by the United States**.

The root server is primarily used to manage the home directory of the Internet. All IPv4 root servers are managed by ICANN, an Internet domain name and number allocation authority authorized by the United States**, which is responsible for the management of IPv4 root servers, domain name systems and IP addresses for global Internet domain names.

There are only 13 IPv4 root name servers in the world, one primary root server is in the United States, and the remaining 12 are secondary root servers, of which 9 are in the United States, 2 in Europe in the United Kingdom and Sweden, and 1 in Asia is located in Japan. These 13 IPv4 logical root servers can command web browsers and email programs such as Firefox or Internet Explorer to control Internet communications.

What would the world look like if the U.S. shut down root servers and shut down the internet?

Downstairs is right.

Therefore, when we use the US server, we use the genuine win system in the United States, so the use of the US server has to add money to use the system.

Because they're internet bigwigs, it's that simple.

I use dynamic IP every day, there are many lines, ** it is not expensive, and the quality is quite stable.

The main thing is not which software is good, but more suitable for your work, domestic dynamics, 5000 lines, convenient.
