Domain name system (DNS) is the system that is used to transmute human-memorable domain names like globalhacknews.com and hostnames like support globalhacknews.com into the identical numeric Internet Protocol (IP) addresses as well as to recognize and locate computer systems and devices on the Internet.
If you use an alphanumeric address like “globalhacknews.com” your computer demands to read what numerical IP address it should communicate to show up the content (for example 151.101.0.121 the IP for globalhacknews.com)They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses.
This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses. Domain name server is a server effective for keeping the file that contains data about the domain name(s) and corresponding IP addresses (zone file) as well as for providing the above-mentioned information during DNS queries.

Start by opening the Command Prompt tool and then typing the following:
nslookup globalhacknews.com
…which should return something like this
Name: globalhacknews.com Addresses: 151.101.0.121 151.101.0.121 151.101.0.121 151.101.0121
DNS Root Servers
There are a number of DNS servers positioned within the connection of computers that we call the internet. Most important are 13 DNS root servers that store a complete database of domain names 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, one in London, one in Stockholm, and one in Japan.
Why You Might Want To Use Third-Party DNS Servers
As we’ve learned over, you’re apparently doing your ISP’s default DNS servers. Still, you don’t have to. Alternatively, you can use DNS servers run by a third party. Pair of the most popular third-party DNS servers is OpenDNS and Google Public DNS.
Still, the original speed varieties yourself see will vary depending on how far you are from the third-party DNS servers and how fast your ISP’s DNS servers are. If your ISP’s DNS servers are fast and you’re found a long way from OpenDNS or Google DNS’s servers, you may see slower DNS resolves than when using your ISP’s DNS server.
