What is DNS?
DNS – also known as the Domain Name System – helps your computer locate and connect to the right website by translating domain names (website names ending in .com) into IP addresses.
How does DNS work?
DNS is made up of a wide network of servers that sustain a database of domain names and their website addresses. DNS then translates the website name into its corresponding address where the website is located – known as its IP address. The goal for DNS is to serve as a directory or index that helps you locate and connect to the right website when you are browsing the internet.
What are the different types of DNS records?
A Record – The record that holds the IPv4 address of a domain name. The Address record resolves domain names, like yoursitename.com to specific IP addresses.
AAAA Record – This record holds the IPv6 address of a domain name. It also resolves domain names to their specific IP addresses.
CNAME Record – This CNAME record creates another name that is associated with the domain name, but it does not provide an IP address. For example, “www.___.com” and “__.com” are associated.
MX Record – The Mail Exchanger record directs the email to the correct mail server. It identifies which mail servers are in charge of accepting incoming mail for a domain.
TXT Record – The Text record lets the domain administrators add and store text to their DNS records. A common use of TXT records is to ensure security for emails.
NS Record – The Name Server record stores the name server for its corresponding domain. These name servers store important DNS information that DNS resolvers use to handle queries for that domain.
What is DNS caching?
The temporary storage of Domain Name System information to speed up future lookups on that domain. DNS caching temporarily stores information about previous DNS queries for a certain period, which helps save time when browsing on the internet.
What is an IP Address?
An IP (Internet Protocol) Address is a series of numbers that correspond to their domain names and serve as a location and label that help our computer identify and connect with the DNS.
What are some examples of places you would change your dns? (godaddy, domain provider etc.)
Some places where you would be able to change your DNS are through Cloud service providers like the Google Cloud Platform, Apple’s DNS server in the Mac operating system, and Microsoft Azure.
