What is a domain name and what is it used for?

What is a domain name?

I believe many people will have this question. When everyone sees the word domain name for no reason, they will be full of doubts and curiosity. In fact, domain names are something we come into contact with every day, and as long as you go online, you have come into contact with it, but you just don’t know it. It is in the URL bar on the web page opened on our computer. This is the domain name address, which is the address you visit this website, as shown in the figure below:

A domain name is simply the website address of a website. It is like a license plate number or a house number. It is derived for the convenience of everyone's memory. It is the way to your website. Before the domain name appeared, it was displayed with an IP address, but the disadvantage is that a string of numbers is too long to remember. In this way, a domain name that is easier to remember and more vivid appeared. The first domain name in the world was registered in 1985. Domain names are usually composed of a string of characters and suffixes. Common suffixes include .com, .net, and .cn. Net was the first to be registered in the world, and com is the most popular and widely recognized domain name. Domain names can also be divided into two categories: international and country domain names. Domain names with three letters or more are classified as international, and domain names with two letters are country domain names, which are managed by the country and regulated by local laws. In general, a domain name is an identity identifier of a computer or group on the Internet, used for electronic location identification when transmitting data. The server host is a computer service device used to serve PCs on the Internet.

So what is the use of domain names?

With the development of the Internet to today's advanced and rapid, and the establishment and rise of various large and small enterprises, and the increasing use of personal websites, everyone has also noticed the importance of domain names. A good domain name can play a protective role. Domain names are important identifiers for online units and individuals on the Internet, and play an identification role, making it easier for others to identify and retrieve information resources of a certain enterprise, organization or individual, so as to better realize resource sharing on the Internet. In addition, domain names can also play a guiding, publicity, and representative role; if your company or product does not improve the protection of the domain name as soon as possible and is registered and used by others, then when others search for your company or product, they will also enter other people's websites and cause traffic and revenue losses. At this time, the price of buying it back from others at a high price may be very expensive. There are many examples. JD.com bought it back for more than 100 million yuan, and Xiaomi Taobao's domain name also cost several million, etc., so the role of domain names is very large, and now it is also taken very seriously by everyone.

Of course, in addition to being used for protection, another major use is to build your own website and invest. Domain name investment has now become an industry, with thousands of domain name investors and collectors active in the domain name world, and some domain name tycoons rely on domain names to make a fortune in life. The domain name industry is also one of the hottest industries nowadays.
