Question

DNS records should be classified. Describe each one, providing examples and the reasoning for its usage. Is it feasible for a company's mail server and web server to use the same hostname as its website?

Expert Solution
Step 1

Definition:

Globally, IP addresses are converted to domain names that can be read by humans via DNS.

A user's web browser or application makes a DNS Query against a DNS server, providing the hostname, when they attempt to visit a website address like "education.com".

The hostname is sent to the DNS server, which converts it into a web browser-compatible IP address.

In order to give crucial details about a domain or host name, including its most recent IP address, DNS servers construct a DNS record.
