Servers China run special software and communicate with each other using special protocols.
- What is a DNS server?
A DNS server is a computer server containing a database of public IP addresses and their associated hostnames and in many cases, serves to resolve, or translate, those popular names to IP addresses as required.
DNS servers operate special software and communicate with each other that use special protocols.
For example: A DNS server on the internet is the device which translates that www.serverchina.com you type in your browser to the 151.011.139.321 IP address that it really is.
Notice: Other names for a DNS server is: name server, name-server and domain name system DNS servers China.
- Why do we have DNS servers?
This question can be answered with another question: Is it easier to remember 151.011.139.321 or www.serverchina.com? Most of us would say it is far simpler to remember a word like ‘serverchina’ instead of a series of numbers.
When you enter www.serverchina.com into your web browser, all you have to remember and understand is the URL http://www.serverchina.con. The same is true for any other site like Amazon.com, Google.com and so on.
The opposite is also true too, that while we as humans can understand the words in the URL far easier than the IP address numbers, other network devices and computers understand the IP address.
Thus, we have DNS servers since we not only want to use human-readable names to access sites, but the computers need to use the IP addresses to access sites. The DNS server is that translator between IP address and hostname.
- DNS Root Servers
There’re a number of China DNS servers located within the connection of computers that we call the internet. Most important are 13 DNS root servers which store a complete database of domains and their associated public IP addresses.
These top-tier DNS servers are named A through M for the first 13 letters of the alphabet. Ten of these servers are in the US, London, Stockholm and Japan.
