First, what is the international domain name The domain name is the name of the computer that is connected to the Internet, which is equivalent to the so -called IP address on the Internet. Domain names are usually used as a shortcut to search for information on the Internet. Here are some examples of domain names you may already be familiar with: Yahoo (belonging to Yahoo) AOL (belonging to American online company)
. What is the difference between international domain names and domestic domain names? The international domain name is the common name for the universal domain name that users can register. Its suffix is, or or. The domestic domain name is different from the Chinese domain name. The domestic domain name is also known as the CN domain name. It is a domain name for suffix. It is a level lower than the international domain name. The registration agencies are different, and there is basically no difference in use. It is just that individuals cannot register domestic domain names. When registering, if you apply for .gov, you need to submit some materials (the application domain name table and the institutional code certificate of the application unit) after applying for the domain name), you need to mail the above materials to our post -domain name to succeed.
. What are the domestic domain name registration conditions? 1) The applicant of domain name registration must be an organization registered in accordance with the law and can independently assume civil liability. Individuals cannot apply for registered domain names. Various contacts in the domain name registration application form are all issues that represent the domain name registration application. The domain name organizer does not apply for the domain name registration application as a personal identity, but represents the organization. 2) What conditions do foreign companies or institutions need to register domain names under CN's secondary domain name? The main domain name server is located in China.
. What is the difference between domain name owner and domain name management contact person? The domain name owner and domain name management contact is different concepts. Among the domain name WHOIS retrieval provided by any level of registers, the first item is the domain name registrar and the domain name owner. The second item is the domain name management contact person, and then the domain name technology and paid contacts in turn. When registering, the domain name owner can request all these contacts to themselves and leave their own electronic mailbox address. However, this has left hidden dangers for security. The reason is that the domain name owner can apply for the registration information except the domain name management contact or technical contact person. Why does the first -level domain name registrar judge whether a modification application is true or from the domain name owner? The criterion for judgment is whether the email address requested is consistent with the domain name management contact mailbox in the registration information. This method is the most unreliable due to fake. In order to improve security, NSI and others advocate that users use PGP encryption, that is, it requires the contact person to send its public key to NSI in advance, and then perform electronic signatures on the information issued by each time to show authenticity. Given that most of China's domain name registrars are not familiar with PGP or other password encryption, the first host is based on the purpose of solving difficulties for users. It serves as a domain name management contact and technical contact person to complete all the above requests on behalf of customers. As a payment contact, online companies solve the many troubles of currency conversion and bank remittances for the domain name consumers. In addition, most Chinese domain consumers are not good at foreign languages. They are in contact with online companies, but they save their communication obstacles. It is also possible to change the domain name management contact to yourself, but we will no longer be responsible for the security issue of this domain name. If you have any questions about this matter, you can contact us directly. All in all, the domain name you register belongs to you, and there is no problem. The domain name management contact of this domain name is our company, and we just manage the domain name for you.
. What characters can be used in the registered international domain name? : 26 letters in English and 10 Arabic numerals, and the horizontal bar " -" (minus number) can be used as a domain name. There is no difference in lethals of letters. However, the domain name cannot exceed 63 characters, and the "-" (minus number) cannot appear at the forefront or last of the string.
. When can it be officially effective after registering the domain name? : The international domain name you registered online, after receiving your registration fee or fax fee confirmation, you can take effect, but after you register online, you will choose the domain name you choose during your paid period. It may be successfully paid by other registered agencies, so we recommend that you pay the fee as soon as possible to avoid losing your valuable domain name.
7. When can the registered domain name be officially effective? E each computer has one or more positions for the position of the computer on the Internet, which is called an IP address. IP address, such as: 204.234.212.1. This positioning system is more annoyed and difficult to remember for humans. If you have domain names, you can not remember the IP address.
8. Who is the international domain name management agency icann is a non -profit institution established in recent years and replaced by NSI. Its main functions include the management of the Internet domain name and address system. Information about icann can be queried in the website: icann.
9. What is the domain name address server (that is, DNS) domain name server to translate domain names into computers to identify IP addresses. For example, if someone wants to access the "first host" website (), DNS translates the domain name to IP address 61.145.118.200. This is convenient for the website server of the computer to find the domain name owner. Therefore, you can also tie the domain name on the virtual host you applied to access your website normally.
Ten, the structure of the domain name The top domain name
The domain name is composed of two or more words, which is separated from the point number in the middle. The word on the far right is called top -level domain name. Below are several common top-level domain names and their usage: *.com-for commercial institutions. It is the most common top -level domain name. Anyone can register a domain name .com form. *.NET-was originally used for network organizations, such as Internet service providers and maintenance providers. Now anyone can register a domain name ending at .NET. *.org-was depends on various organizations, including non-profit organizations. Now anyone can register a domain name ending at .org.
State code
The top domain names composed of two letters such as, .uk, .de and .jp called the top domain name (CCTLDS) of the national code, of which it was dedicated to China The top -level domain name is registered to CNNIC management, and we are referred to as the domestic domain name in the secondary domain name. The rules and policies of the second -level domain names under the top -level domain name of the national code are related to the policies of different countries. When you register, you should consult the domain name registration agency to ask the relevant registration conditions and the relevant terms related to registration. In addition to providing the registration service of the end domain name, some domain name registry also provides registration of top domain names of the national code. ICANN did not specially authorize registrar to provide registered services for top domain names in national code.
The second -level domain name
The next level of the top domain name is what we call the secondary domain name. The domain name registrar provides a secondary domain name in the top -level domain name. The domain name form may also be something. In this case, Something is called the main name or domain name. ■ What is the virtual host
The so -called virtual host is to divide a server running on the Internet into multiple "virtual" servers. Each virtual host has an independent domain name And the complete Internet server (supports www, FTP, E-mail, etc.). Different virtual hosts on a server are independent and managed by the user by themselves. However, a server host can only support a certain number of virtual hosts. When exceeding this number, users will feel that the performance decreases sharply.
■ The hardware conditions of the virtual host
The trial: virtual host service provider generally provide a few days of trial time before the user purchases its service. During the time, understand the performance of the virtual host, and select a suitable "big family" for your webpage and email.
: The virtual host of about 100 users with a telecommunications backbone line is much faster than those independent hosts connected to low -speed line connections such as ADSL.
The stability: Of course, in addition to speed, we must also pay attention to the stability and security of the network environment. For example, whether the service provider uses Cisco and 3COM routers to connect to the network, whether the gateway firewall is purchased, whether Whether there are people who monitor various attacks from the Internet 24 hours a day ... Only host service providers with the above conditions are the goals we choose.
It some virtual host service providers to find low -bandwidth routes, then make some equipment, find two technicians who know how to debug Windows 2000, and then rush to provide services. Even if its price is cheap, we don't recommend it.
The service stability is derived from the infrastructure of the service provider. Configure a higher -grade server, equipped with redundant devices, RAID cards, etc.; There is a guarantee of stable UPS, emergency generators in the power supply; equipment that maintains constant temperature, constant humidity, and so on. Of course, these hardware facilities are sometimes impossible to see them with their own eyes. Therefore, it is important to understand the situation of service providers through multiple channels (such as service providers' websites) before buying! After all, you can find a suitable host!
■ How much space do you need
The type of virtual host server provided hard disk space is divided into independent web space, database space, independent post office space, etc. The size of the virtual host space is mainly based on the information published. If your website contains about 10 to 150 pages, each page is counted as related pictures, and there are more than 100 KB, then you rent 60MB of space. If the page is more than hundreds of pages and you need database support, then the corresponding space you need should be between 100MB and 200MB. When the actual space is insufficient, you can make up the difference to apply to the service provider's application to increase the size of the space. If the purchase space is very large at the beginning, it will not be used so much.
■ The software conditions of the virtual host
The server of the virtual hosting host generally use Windows 2000 (NT) and Unix (Linux). Essence Database spaces are also divided into two categories: IIS 5.0/Access database space of the Windows 2000 platform and mysql/PHP database space on the Linux platform. However, the author is more inclined to choose Unix (Linux), but for companies that often call various databases and need to be designed in ASP web designs, they can only use the Windows 2000 platform. The Unix system supports PHP.
China's top domain name (commonly known as domestic domain name) refers to the domain name of suffix. There is basically no difference in the use of the two, but there is no conditional restriction in registered international domain names, and both units and individuals can apply. The so-called virtual host is to divide a server running on the Internet into multiple "virtual" servers. Each virtual host has an independent domain name and a complete Internet server (supports www, FTP, E-E- Mail) Function. Different virtual hosts on a server are independent and managed by the user by themselves. However, a server host can only support a certain number of virtual hosts. When exceeding this number, users will feel that the performance decreases sharply. The virtual host uses special software and hardware technology to divide a server host running on the Internet into a "virtual" host. Each virtual host has an independent domain name and a complete Internet server (WWW, FTP, FTP , Email, etc.) Function, virtual hosts are completely independent, and can be managed by users themselves. From the outside world, each virtual host is exactly the same as an independent host. Shengwei Network provides high -quality network environment and servers for small and medium -sized customers, and is responsible for monitoring by high -end network management.
