Human-readable hostnames are converted into IP addresses by the Domain Name System (DNS). It also offers additional helpful information on domain names, like mail services.
In other words, DNS functions as an online phonebook. You can easily look for someone's phone number in a phone book if you know their name but not their number. This service is also offered by DNS. For any business that uses the Web to connect with clients, partners, suppliers, and workers, DNS is essential.
There is a variety of DNS and DHCP solution for enterprises available. You can any the one according to your business needs.
Why Is DNS Important?
So what makes DNS so crucial? Due to its crucial function as the internet's skeleton, DNS is significant. You won't be able to access other websites on the internet if a DNS is down.
This is because you do not have to worry about remembering and typing in a long number when a web browser is launched and the desired website is to be accessed (IP address). Just input a domain name, and you'll get exactly where you need to.
No website will be accessible if the DNS is unable to map the domain name to the proper IP address. Simply, most of the internet as we know it fails without DNS. DNS makes sure that the internet is not only user-friendly but also operates efficiently, loading whatever content we request promptly. It serves as one of the pillars on which the internet is built.
Without it, to access the content we want, we would be forced to memorize extensive lists of numbers (IP addresses). You won't be able to visit the website you're looking for if a DNS service is unable to convert the domain name to the correct IP address.
The Evolution of DNS
Even though most people are unaware of what DNS is or how crucial it is, it nevertheless remains a vital part of the internet.
It has grown so crucial that IT giants like Google and Mozilla now ship their browsers with HTTPS (HyperText Transfer Protocol Secure)-encrypted DNS as standard. End-to-end encryption offered by this protocol ensures the secrecy of data and safeguards users while they are online.
HOW DOES DNS WORK?
DNS resolution includes translating a hostname (such as www.example.com) into an IP address that computers can understand (such as 192.168.1.1). Each Internet-connected device has an IP address, which is required to identify the correct Internet device, much as a street address is required to identify a certain residence.
A translation must take place between what a user types into their web browser (example.com) and the machine-friendly address required to find the example.com webpage when they wish to load it.
