What is DNS?

DNS stands for Domain Name System. It is a system that translates the domain names you enter in your web browser into the IP addresses that computers use to communicate with each other. This allows you to access websites using easy-to-remember names, rather than having to remember the numerical IP addresses of the websites. DNS is an essential part of how the internet works, and without it, you would not be able to access any websites using a domain name.

What is an A Record?

An A record is a type of DNS record that maps a domain name to the IP address of a computer that is hosting the domain. When you enter a domain name in your web browser, the browser contacts the DNS server and requests the IP address associated with the domain name. The DNS server responds with the A record, which contains the IP address, and the browser uses that information to connect to the correct website.

What is an MX Record?

An MX record is a type of DNS record that specifies the mail server responsible for accepting email messages on behalf of a domain. The MX record contains the domain name of the mail server and a priority value, which indicates which server should be used if there are multiple servers available. When someone sends an email to a domain, their mail server looks up the MX record for the domain to determine where to deliver the email. This allows emails to be delivered to the correct mail server, even if the domain name itself does not include the name of the mail server.
