What is a domain name

​Domain name is the “address” and “name” of the website on the Internet.Its main purpose is to make it easier for us humans to remember and access websites.

Why do you need a domain name? What happens without a domain name?

Imagine if you were looking for a friend and the address he gave you was not “No. 1, So-and-So Street, Chaoyang District, Beijing”, but a long list of random numbers, such as61.135.169.121How would you feel?

It's hard to remember, isn't it?

The Internet world is no different. Virtually every computer and server connected to the Internet (which can be understood as a mainframe hosting the content of a website) has a unique numeric address called theIP address. It looks like the string of numbers above. You want to access Baidu's website, which essentially means that you're asking your computer to connect to Baidu's server IP address.

But if you're asked to memorize 123.135.109.521to access LikaCloud, instead of typing www.likacloud.com, that internet access would be a pain in the ass!

So.Domain names were invented to solve the problem of “IP addresses are too hard to remember”.. It uses meaningful combinations of English words, numbers, and symbols (such as yunzhehui, google, taobao), to replace the boring and difficult to memorize numerical IP addresses.

​Simple analogy.​

• ​IP address= Latitude and longitude coordinates of the house (very precise, but difficult for humans to memorize and use)
• ​domain name= House number, e.g. “888 Happiness Road” (human-friendly, easy to remember and relay)

How do domain names work? (DNS: Domain Name System)

You may ask, “Computers only recognize IP addresses, so how does the computer know where to go when I type in my domain name?”

There is a very clever and important “translator” working behind the scenes.DNS (Domain Name System)。

The process is exactly the same as if you were navigating with a cell phone map app:

1. ​You enter the domain name in your browserFor example, if you want to visit Baidu, you type in the address bar www.likacloud.comThen press enter.
2. ​Browser Help DNSYour computer doesn't know. www.likacloud.comWhere is it, so it immediately asked the “Global DNS Navigation System”: “Hello, please! www.likacloud.comWhat is the actual IP address that corresponds to this address?”
3. ​DNS query and return results: The DNS system looked up its records in the global network of servers and quickly found the corresponding IP address to be 123.135.109.521, and then tell your computer the result.
4. ​Computer to correct address: Once your computer gets the IP address, go straight to the connection 123.135.109.521This server. Baidu's server then sends the content of the website to your computer and the page is displayed in your browser.

The whole process is so fast and almost instantaneous that you can't even feel it.

​So, DNS is a giant, globally distributed “address book” or “navigation system” responsible for translating human-friendly “domain names” into machine-friendly “IP addresses”. "IP addresses.​
