Example of using the api.ipify.org API in the JSON format
Optional text version of the API would be more straight forward,
this demonstrating some manual parsing of the JSON format.

JSON format can also be converted to a PowerSHell object via 'convertFrom-Json' cmdlet:
 (Invoke-WebRequest -URI https://api.ipify.org?format=json) | ConvertFrom-Json | Select-Object


#>
 
# get today's date in a nice string format, and store it in a variable
$date= Get-Date -Format 'yyyyMMdd.hh.mm'

# path that we're going to write the resultant file to, including a date stamp
$path_of_export = "C:\test\$date.testing.csv"


# 'invoke-webrequest' is similar to 'wget' in BASH, infact it has the alias of 'wget' in PowerShell
# splitting on '"' in the 'content' property of the returned object and storing the resultant array in the '$IPlookUP' variable
$IPlookUP = (Invoke-WebRequest -URI https://api.ipify.org?format=json).content -split '"'

# grabbing the third element in the array which contains the IP
$IPlookUP[3] |

# performing a calculated property with 'select-object' to associate 'IP' as the property name with the value of the IP
 Select-Object @{name='IP';expression={$_}} |

# writing the selected object to a CSV export
  export-csv -NoTypeInformation -Path $path_of_export

# Letting the using know the file name created
write-host ""
write-host "File written to " -NoNewline ; write-host -ForegroundColor Green $path_of_export
