IP Ping VBA/VB.NET

Hi i have 33 network attached storage on my network over a spread location. i currently have a spread sheet of them all with there IP addresses. Basically what i want to do is when i open the spreadsheet or application i need to know whether the NAS is still live. So maybe when i open the spreadsheet in the background it automatically pings all the addresses and then in the cell next to the corrosponding ip address state whether its active or not with colours maybe. I dont know whether this would be easier in excel VBA or visual studios VB.NET. But currently im stuck on how to do this. If anyone has any knowledge of this would be great and maybe an example of 1 IP ping in either application so that i can replicate myself or something. Thanks Guys
