Using Ping for Network Connectivity

The first thing we are going to do is use ping to test our internet connection. We will ping Google and see how fast our internet connection is. With Command Prompt open, type “ping google.com” without the quotes and hit enter. In the image below, you can see the results. A ping command sends a request over the network to a specific IP address or device. In a successful ping, the computer that was pinged responds to the computer that initiated the ping. An overall summary will show you how many packets were sent and received, along with the minimum, maximum, and average response times. This is ping at its most basic.

How to Flush and Reset the DNS Cache in Windows 10

Flushing the DNS resolver cache can help resolve DNS related problems in Microsoft Windows 10. Each time you visit a website with its domain name, your browser retrieves its IP address from the DNS server. It then redirects you to that website. If you visit that page again, Windows remembers what IP address it points to so you can access the information faster next time you visit. These records make up the DNS Resolver Cache.

It is possible for an IP address associated with a site to change. A DNS Resolver Cache that contains an outdated IP address entry may prevent your computer from getting to the site. It is also possible for cached data to become corrupt. If you cannot access a particular website, flushing the DNS cache could be a solution to the problem.

Type ipconfig /flushdns then press Enter.
