DNS, DNS Server, as many of you know, stands for Domain Name System, and is the system used to assign an IP address to a domain name.
Every computer online has an intellectual property (IP) address; this address is a string of numerals and periods e.g. 180.156.0.1.
A DNS system with a domain server resolves this address to a domain name made up of words like www.mysite.com. Let’s check out the purpose of the dns server below.
The purpose of the dns server
The purpose of DNS servers and systems is to translate human readable domain names into machine readable IP-addresses. The concept was put in place so that people don’t have to remember confusing numbers to access a website.
This knowledge isn’t required if you simply want to get a domain name for your website. Your website will work just fine even if you don’t understand the concept of DNS or IP addresses or any such thing.
However, being aware of these concepts will help you a great deal in troubleshooting and solving any technical problem that you might face with a website down the line.
Understanding DNS
Having a good understanding of the mechanism of Domain name system servers and addresses can help you solve most networking problems that people encounter at their homes.
There are times when the connection seems dead in the browser, but everything seems fine at the modem. Situations like these point to a problem with the settings for the Domain name system server.
When you enter a web address, and you aren’t connected to a good DNS server, it is possible that your computer won’t know where to go to look for that website.
All the websites and domain names on the internet are organized with the help of IP addresses.
As long as a website is associated with a particular IP address, a Domain name system server can help your machine locate the website.
However, if the DNS server doesn’t have information about a website’s IP address, there is little it can do to route your request to the appropriate website.
DNS servers are broadly classified as public Domain name system servers and private Domain name system servers.
Due to their open nature, public Domain name system servers can be accessed by any computer connected to the internet.
They are usually managed by different volunteers who don’t charge any money for their services.
These servers often use FreeBSD servers which are adequately backed up with a UPS (uninterruptible power supply).
Simple actions like sending an email or browsing the web make use of a DNS server. This process goes on behind the scenes, and may not be obvious to casual computer users.
However, it is a critical system, as without it the internet as we know it would not exist.
Whenever someone types a domain name into their address bar or clicks on a link, the Domain name system server is called upon to retrieve the human-readable information and translate it into a machine-readable IP address.
