There are two files, PingProgram.docx and GetHostByName.docx. PingProgram needs an IP address to work, and doesn't use URLs, as per the example below. GetHostByName will return an IP address given a URL, also shown below. GetHostByName takes in a URL and a port number.

Rewrite PingProgram to do the following:

2. Accept either a URL or an IP address as an input.
4. Ping the requested server 3 times instead of once.
6. Present all 3 round trip times, along with an average round trip time.

PingProgram example:

PS C:\Users\STARID\source\repos\PingProgram\Debug> .\PingProgram cnn.com

usage: C:\Users\STARID\source\repos\PingProgram\Debug\PingProgram.exe IP address

PS C:\Users\STARID\source\repos\PingProgram\Debug> .\PingProgram 151.101.129.67                                              Sent icmp message to 151.101.129.67

        Received 1 icmp message response

        Information from this response:

          Received from 151.101.129.67

          Status = 0

          Roundtrip time = 31 milliseconds

 

GetHostByName example:

PS C:\Users\STARID\source\repos\GetHostByName\Debug> .\GetHostByName cnn.com 0

Calling getaddrinfo with following parameters:

        nodename = cnn.com

        servname (or port) = 0

 

getaddrinfo returned success
