Using the Internet has become very easy in the past few years, due to the latest technology and better algorithms. As you type in a domain name, a lot goes on behind the scenes to redirect you to that domain. When you search on the internet, you will write a domain name like and you are taken to Amazon. However, a lot of processes take place as you type in that domain name.

The Internet connection is routed through servers and these servers do not understand or other domain names. They only understand IP addresses that are written in numbers. As users, you cannot remember the IP addresses for every website so there has to be a translator that translates your message to the network servers.

What is DNS?

DNS or Domain Name System translates the domain names such as to IP addresses so that the network servers can understand where you want to go on the Internet. If you have an Internet connection at home, your Internet Service Provider normally also provides a DNS server for your connection. When you type a domain name, it gets sent to the browser.

The browser sends this information to the DNS server and the server translates it into a numeric IP address that is verified. Since the message has been converted to numeric form, the server can now redirect you to Amazon’s website.

Problems with DNS

As you might have figured out by now, DNS is an important component of any network. So, if anything is wrong with the DNS, your connection will be weak or terminated. If the DNS supplied by your Internet Service Provider is slow, you will see a delay in page loading. This is especially true for those websites that show you content from different affiliate sites or advertisers. These domains take much longer to load.

Secondly, network admins can also have add-ons with the DNS. These add-ons can filter out malicious sites so that your browser is never redirected to a certain site. If there are any inappropriate sites like porn, they can also be filtered out. Parents can also use DNS for parental control over what their children can access on the Internet. In this way, they can restrict age-inappropriate content. If anything goes wrong with the DNS, it could cause issues.

Some ISPs monetize the DNS that they provide to their network users. How this works is that if you type in a domain name that does not have an IP address, you will be taken to another page on which the ISP has put advertisements. It should not really matter if the ISP is displaying advertisements but some people are concerned about their privacy.
