If you are keen to learn the difference between a DNS and Nameservers, then you might need to consider the following information:
The DNS (Domain Name System) is a system that consists of the biggest digital database on the planet. This massive database is managed and maintained by few internet authorities, including the IANA (Internet Assigned Numbers Authority) and ICANN (Internet Corporation for Assigned Names and Numbers).
Many people confuse the different terms associated with the DNS and mistakenly refer to them as either the same thing or totally different. In reality, they are neither separate nor are they the same thing; rather, they are necessary pieces to the puzzle that is the world wide web.
What is DNS ?
As opposed to an apparently mainstream misinterpretation, DNS does not stand for Domain Name Server or Domain Name Software. It’s an expansion for the previously mentioned system that catalogs IP addresses and domain names on the internet, including required registration data, as well as their relation to other domains and web hosts.
DNS is a protocol through which computers exchange data or information with each other over the Internet. The basic working of DNS is to convert a domain name into an IP (Internet Protocol) address i.e. : www.techzib.com to 126.96.36.199. Computers identify each other through IP addresses. It is same like using a phone number of a person you are trying to call. As It is very difficult for us to remember an IP address of a website. SO our request is mapped through a DNS server.
What is DNS Software?
DNS software is a program installed on the web server and used to facilitate the transference of information identified with the domain name system. In fact, any web server can be installed with the DNS software on it, making the server a name server; however, in the case of shared hosting servers, some web hosts won’t permit you to install the software inside your hosting control panel.
If you want to Install DNS software on a web server or you want custom nameservers then you should have a VPS or dedicated hosting or you can buy a private web server if you have a lot of money to invest.
What is a Name Server?
In simple words, name server is a server that has DNS software installed on it, especially a server that is managed by a web host that is particularly assigned for dealing with the domain names that are connected with the majority of the hosting provider’s accounts.
Name servers are frequently called DSN servers too, and this is likely the origin of all of the confusion connected with name servers and the DNS.
A website has two name servers to which it is pointed, and this procedure must be finished by the website admin after purchasing a domain name and hosting.
What Are DNS Records?
A – Address : A records are the most important records by far and connect a domain name to is numerical IP address. If you do not have A records your domain name can not be converted into IP address.
Note : Some hosting providers ask you to enter a period after the hostname.
CNAME – Canonical Name
CNAME allow a server to be known by one or more hostnames. These records act as the alias for the domain set up in the A record. Basically they are used to connect sub domains with the existing domain’s DNS records.
MX – Mail Exchange
Mail Exchange (MX) records indicate a mail server in-charge of managing all the email messages on the behalf of the domain name. You can enter unlimited servers to try.
Almost all the hosting providers guides us exactly what should be put here. If you are using Gmail or other service they also explains what to enter.
