A good horse needs a good saddle.

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; The network is based on TCP/IP protocol for communication and connectivity, each host has a unique identity fixed IP address, to distinguish between thousands of users and computers on the network. The network uses a unique, universal address format to differentiate all connected networks and hosts, that is, each computer and server connected to the network is assigned a unique address. In order to ensure the uniqueness of the IP address of each computer on the network, the user must apply to a specific institution for registration, which assigns the IP address according to the network size of the user unit and the recent development plan. The address scheme in the network is divided into two sets: the IP address system and the domain name address system. These two sets of address systems are actually one by one corresponding relationships.

The IP address is represented by a binary number, each IP address is 32 bits long, consisting of 4 numbers less than 256, with a dot interval between the digits, for example, 166.111.1.11 represents an IP address. Because the IP address is a digital ID, it is difficult to remember and write when it is used, so a symbolic address scheme is developed on the basis of IP address to replace the digital IP address. Each symbolic address corresponds to a specific IP address, so the resources on the network are much easier to access. This is the character-type address corresponding to the digital IP address on the network, which is called the domain name.

Visible domain names are the name of the Internet unit, is a computer to board the network of units in the address of the net. If a company wants to establish its own home page on the network, it must obtain a domain name, which is composed of several parts, including numbers and letters. Through this address, people can find the required details on the network. Domain name is an important sign on the network of Internet units and individuals, which plays a role in identifying and retrieving information resources of an enterprise, organization or individual, so as to better realize resource sharing on the network. In addition to the recognition function, in the virtual environment, the domain name can also play the role of guidance, publicity, representative and so on.

The value of a good domain name without the author said more, such as: g.cn qq.com and so on, now basically extinct. Now the most popular online is the CN domain name, because the cost is too cheap, is generally the first year only a piece of money, and some even free gift (dolob.cn is the author has been free of a domain name). Plus a 100M space but dozens of yuan, and like some free space quality is still very high, such as the portal to free to give webmaster 2G quality space. Therefore, a webmaster's "baked" cost, has been basically self-made.

When it comes to doing websites, general webmaster friends will inevitably and headache domain name and space, we all understand a domain name if the election is good, it will be an excellent brand, and the longer the more valuable, become a site of intangible assets. In contrast, the choice of space relative to the domain name is more extensive. Because even if the site is black, but as long as there is a domain name is not afraid, you can make a comeback. If the domain name by the search engine K, this situation to the impact of the site is relatively large. For a considerable number of websites, this can be said to be the "site" sentenced to death. After all, about 80% of the traffic from most Web sites comes from search engines.

As the saying goes: good horse with a good saddle. Therefore, we can play a metaphor, good domain name is a horse, and good space is a good saddle. about how to register a good domain name and how to judge a domain name pros and cons, the author will be in the next article on the step-by-step introduction. And good space as a basis for a website, pick up, but also bother, however, for the majority of small and medium-sized webmaster, if you can have a free high quality space, coupled with the good domain before, in the Internet under the sky, is not it?
