I found my way here after getting to the permissions exceptions, and this explained nicely how to fix that. I'm actually solving the exact same problem, so that we can track the client machine hostname in our ISA web proxy log. One minor modification to this code would be to add .Trim() to the ipaddr parameter. I noticed a number of the ips failing to resolve when I first ran this on real data. That's because some of them had trailing spaces in the string. If you pass an untrimmed string to Dns.GetHostEntry, it will fail to resolve. So just change: string myIP = System.Net.Dns.GetHostEntry(ipAddress).HostName.ToString(); to string myIP = System.Net.Dns.GetHostEntry(ipAddress.Trim()).HostName.ToString(); and it all works peachy.
