Rebirth, I am the most powerful business tycoon

DNS root server, also called IPV4 server or root domain name server.

Mainly used to manage Internet directories.

It is based on UDP and TCP protocols.

UDP is usually used for queries and responses, and TCP is used for transmission between the master server and slave servers.

Since the maximum length that is guaranteed to work properly in all UDP queries and responses is 512 bytes, 512 bytes limits the number and names of root servers.

All root server data must be contained in a 512-byte UDP packet.

IPv4 root servers are limited to 13.

And each server is named using a single letter of the alphabet.

This is why IPv4 root servers are named from A_M.

The top-level domain name resolution service of the Internet is completed by the root server.

Root servers are crucial to network security and operational stability, and are called the”central nervous system” of the Internet.

Before the root server appeared.

The website is accessed through the IP address.

However, the IP address is too long and difficult to remember. Later, someone developed a root domain name server through domain name.

That is, the commonly visited domain name suffixes such as com, cn, and org are freely combined with numbers and English.

For example, taobao, baidu, etc. can register domain names through DIY to the greatest extent.

In this way, users no longer need to remember complex and cumbersome IP addresses.

There are 13 root domain name servers, 1 primary root server, and 12 secondary root servers in the world.

Among them, 1 main root and 9 auxiliary roots are in the United States, 2 are in the European Eagle Country and Novi, and 1 is in an island country.

The Internet in Daxia developed relatively late, resulting in the failure to get a share of the 13 root domain name servers.

After understanding this, let’s talk about the importance of root domain name servers.

Because the root server is placed in the United States.

Once the United States disconnects Daxia’s root domain name server, it will mean that Daxia’s Internet will be mid-range.

Although ordinary netizens query domain names.

Basically there is no need to directly access the root domain name server.

Most of this is done by mirroring the root server.

Only when the mirror root server is not queried will the root domain name server make a query request.

There are very few records in the root domain name server. Information about more than 1,000 top-level domain names is recorded, and less than 10 are commonly used.

However, this formed a Daxia LAN.

Only the mirror root server in Daxia can be accessed.

The global Internet is no longer accessible.

To describe it simply, it is like the difference between stand-alone games and online games.

Without access to the global Internet, can we still call it the Internet?

Therefore, how important it is to have a root server.

In addition, information security is also involved.

If Jiang Feng wants to build a global Internet center in Xiangjiang and not follow the same path of the Internet in his lifetime, he must control the root server.

Whether from his own perspective or from Daxia’s perspective.

In this life, he will get the root server no matter what.

Don’t think about the taproot.

The United States definitely disagrees.

The only thing that can make up its mind is the secondary root server.

At present, the 12 secondary root servers have not been used up. Only 6 are used in the United States, and 3 are left.

This was also the reason why he rushed to the United States non-stop to see Lu Shi.

Taking advantage of his current relationship with the United States, he will promote this matter as much as possible.

Lu Shi naturally knows about the DNS root server.

This project was still promoted during his tenure.

Therefore, when Jiang Feng mentioned this matter, he immediately understood what it was about, frowned and said,”What are you doing with the root server? Aren’t you in the industry?”

“Who says you can’t engage in the Internet if you’re engaged in industry?

Jiang Feng smiled and said:”I am very optimistic about this industry and plan to invest hundreds of millions of dollars to play.””

Hundreds of millions of dollars for fun?

” Lu Shi rolled his eyes and gave him an annoyed look.

He thought that this guy just didn’t regard hundreds of millions of dollars as money.

“It is impossible to use the main root server. If you have to intervene, it is not impossible, but it can only be a secondary root server.”Lushi pondered for a while and said slowly.

“Of course.”

Jiang Feng doesn’t even want the main root server.

Unless the Americans are crazy, they will definitely not agree.

Smiling, Jiang Feng said slowly:”I only want secondary root servers, just two.”

“2 units?”

Lushi exclaimed:”Your appetite is too big. Two sets are definitely not possible.”

Lushi refused without hesitation.

If it is TV 1.

Due to his relationship with Jiang Feng and his friendship with this super rich man, under his operation, maybe this matter can be promoted.

After all, before There are 3 cases to follow

“Mr. Lushi, don’t rush to conclusions. Listen to my explanation first.”

“Well, I would like to see what Mr. Jiang has to say. Jiang

Feng smiled and said,”I know what Mr. Lu Shi is worried about!”! I don’t think there’s any need to worry.

The reasons are as follows:

First, Hong Kong is a free trade port. The atmosphere of freedom here is no different from that in the United States and even the world. As a global financial center, the market value of transactions every day is as high as 30 to 40 billion. Isn’t it appropriate to build a secondary root server in such a financial center?

Second, the main root server is in the United States. There is no need to worry about damage to the interests of the United States. In my opinion, even if all the subsidiaries are located in other countries, it will not shake the United States’ position in this field.

Similarly, once the secondary root is located abroad, doesn’t it reflect the United States’ openness to the Internet?

If it is not set up, I believe that other countries will ask for it in the future. Rather than doing this, it is better to set it up in the free port of Hong Kong….”

After a pause and looking at the frowning Lu Shi, Jiang Feng continued:”If Mr. Lu Shi can push this matter forward, I will send a big order to your country.”

“What big order?”

Lushi asked

“I plan to invest in 2 submarine optical cables from the United States directly to Hong Kong. The standards are all designed according to 8 pairs of optical fibers with a transmission rate of 80gb/s for each pair. It is expected to invest 800 million yuan.”

Jiang Feng said with a smile.

Once these two direct-connected optical cables are completed, they will undoubtedly greatly improve the network access speed in Hong Kong, even the mainland, Macao Island, and the Bay.

The transmission rate of 80gb/s is higher than the trans-Pacific submarine one year later. The optical cable is more than four times stronger.

The formulation of high standards played an important role in Jiang Feng’s efforts to build Xiangjiang into a global-level Internet.

As for why two are built, it is very simple. One is for personal use, and the other is for use in the mainland and Southeast Asia. Countries, even island countries, Bangzi and other countries.

Isn’t it good to collect tolls?

This is from the long-term perspective of building second-generation mobile communications and third-generation mobile communications.

Jiang Feng believes that it is necessary to build high-standard.Perhaps

, we can inadvertently create a global telecommunications company comparable to ATT.

Ps: I don’t know if you can understand some of the professional terms, so I checked a lot of information. Some of them are mindless and don’t even have infrastructure. Fight against heaven and earth…
