The DNS Service



DNS (Domain Name System) is a service that translates domain names into IP address, which are used by computers to communicate with each other. 

It acts as a directory that links a domain name to an IP address and enables users to access websites, email, and other internet services using a domain name instead of an IP address.

A DNS server is responsible for converting domain names into IP addresses. 

When a user types a domain name into their web browser, the browser first contacts the DNS cache (local) and then a DNS server to look up the corresponding IP address, and then the browser can communicate with the server hosting the website at that IP address. 

The DNS service is divided in a few different types of Servers:

  • Root
  • TLD
  • Non Authoritative

A VPC allows users to securely and privately connect their cloud resources, such as virtual machines, databases, and applications, to the Internet. This provides the same level of security and privacy as a traditional on-premises network, but with the scalability and flexibility of the cloud. A VPC is essentially a virtual network environment within the cloud provider's network, which is isolated from other virtual network environments. This provides users with complete control over their network configuration, including the ability to define custom IP address ranges, subnets, and network access control lists (ACLs). VPCs also allow users to securely connect their cloud resources to other cloud services, such as storage services or databases, and to other resources in their own on-premises netw...
