Understanding DNS

Before we delve into the problem-solving aspect, it's important to understand what DNS is.

Its basic job is to turn a user-friendly domain name into an Internet Protocol (IP) address.

The first and most straightforward solution is to restart your router. This helps in clearing out any issues that your network may be facing.
