Importance of DNS

In a nutshell, the DNS handles translating human-readable domain names into the numeric IP addresses used by computers and Internet routers. The data is structured in a hierarchical manner and served from 13 clusters of root name servers that services the entire public Internet.

The most important fact to remember is that while DNS information can be cached for varying amounts of time within this hierarchy, only the DNS server serving your domain – known as the authoritative name server, holds the requisite IP address information. In simplified terms, knocking the authoritative name server out of action will disrupt the ability to resolve the IP address.

An inability to resolve an IP address will cause Internet software to fail. And because server-to-server communication also works on the same principle, the affected domain is rendered inaccessible, including the capability to send and receive emails. This is why Internet service providers and hosting companies routinely deploy multiple DNS servers.

The domain name system (DNS) connects URLs with their IP address. With DNS, it’s possible to type words instead of a string of numbers into a browser, allowing people to search for websites and send emails using familiar names. When you search for a domain name in a browser, it sends a query over the internet to match the domain with its corresponding IP. Once located, it uses the IP to retrieve the website’s content. Most impressively, this whole process takes just milliseconds.

IMPORTANCE OF DNS ARE:- The Domain Name is generally the organization that manages the internet domain names. With this the simplest guidance we can do is registering our own domain name very quickly and easily. The importance of Domain Name basically can be defined with the following 3 steps:

1. It’s your “FIRST IMPRESSION”.
2. It affects SEO ranking.
3. It defines your brand.

The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network.
DNS is like a phone book for the Internet. If we know a person’s name but don’t know their telephone number, we can simply look it up in a phone book. DNS provides this same service to the Internet.

Domain Name Service (DNS) points your website onto a particular server, so that it becomes accessible when a end user browses it. The website on which your website is hosted has particular nameservers. You need to set/point the nameservers of your domain to those in order to get your website accessible over Internet.

DNS is know as Domain name service. It is one type of naming system for computer that connected to a network. It is very useful that make an easy way to remember IP addresses. Its help to translate the IP address into name which are easy to read and remember for the visitors.

Domain name system is more More Reliable,faster,and safe this are the most importance of dns and also it is most importantly it's a distributed database. Each DNS server contains only a small portion of the host name to IP address mappings.

Every server has its unique IP address, which is not easy to remember, so a domain name comes into play. Every domain name is recognized by the IP it is designated to and for recognizing this IP of the domain name, DNS comes into action.

According to me DNS system is very important to run internet operations as domain names are for human understanding and can not be understood by computer system. DNS is invented for understanding a domain name to a computer system.

HI,
"DNS" as a kind of phone book for the Internet. If you have a person's name, but do not know their telephone number, you can look it up in a phone book. DNS provides this same type of service to the Internet.
Thanks.

As of me DNS system is very important to run internet operations as domain names are for human understanding and can not be understood by computer system. DNS is invented for understanding a domain name to a computer system.

DNS records are managed in "zones". Every DNS server has files that store the records for a given domain name. The DNS server that handles the records for a specific domain name is called the "authoritative nameserver".

DNS is the important factor in hosting, and domain name., the DNS connects your domain name with the hosting account, so the files hosted by you can be visible by browsing your domain name.

DNS is really important then because we will get lost in the web without the database from the DNS. Is there a possibility that there will be a duplicate DNS in the internet?

Domain naming services .
Which company provide the hosting service, they are also provide DNS?
