More Web Services with PowerShell: Geo IP Location

Now that I have been bitten by the New-WebServiceProxy bug and built the weather function in a previous blog, I decided to work on another function to grab an IP address and show the country of origin. So without re-hashing what I already talked about, I will just go right into the function and show an example of what it can do.

Get-GeoIP -IP 65.68.15.56

ReturnCode        : 1
IP                : 65.68.15.56
ReturnCodeDetails : Success
CountryName       : United States
CountryCode       : USA

You can also view your Internet IP Address using the following command:

Get-GeoIP -ShowInternetIP

Sorry, not showing you the output on that one. Smile
