How to change DNS Settings?

DNS stands for Domain Name Server is the way to maintain a directory of domain names and translate them to corresponding Internet Protocol (IP) addresses which are constantly kept up to date. This is necessary and useful because although people easily remember the domain names, computer or machine access websites based on IP addresses.

Web browsing and most other internet activity rely on DNS to quickly provide the information necessary to connect users to remote hosts.

When you request a domain name through the internet, your computer tries to know where on the internet that domain is situated. Then it sends the request to the DNS containing the name of the domain and gets this information with numeric IP address from the DNS. Then your computer proceeds to connect to that address.

What are the benefits of changing your DNS settings?

  • Sometimes we want to change our default DNS setting on our computer so that we can easily remember the addresses you used for the particular domain.
  • It also act as a good troubleshooting step while solving certain kind of internet connection problem, might help keep your web surfing more private(assuming you choose service that doesn’t log your data), and could even allow you to access sites that your ISP has chosen to block.
  • It filters out known malware sites and is updated quickly as Google discovers bad factor.
  • It’s anycast so that you will get to the network nearest one of many servers.

Procedure:

ISP (Internet Service Provider) which provides its own default DNS for its customers and Internet services include Internet access, Internet transit, domain name registration and the setting for this server are automatically configures via DHCP (Dynamic Host Configuration Protocol).

But luckily you don’t have to use your own ISP’s DNS. Because there are many available free and public DNS server list for a list of primary and secondary DNS server, which you may use one of them instead.
