IP Resolver

[CodeForYourLife!]

Stuck on resolving host IPs within a listbox. I want it to carry over the resolved IP's to listbox2. But also have an 2 radio options either to resolve IP to Hostname or resolve Hostname to IP. Thus when I hit the start button, it checks to see which one is selected and starts the process. Here is what I have found, but can there be a simplified version to this but for lists? http://vbnet.mvps.org/index.html?cod...k/iplookup.htm

You can get the IP address from a host name like so:

Private Function GetIPAddressFromHostName(ByVal hostName As String) As String
    Return Dns.GetHostEntry(hostName).AddressList(0).ToString()
End Function

I thought that the other way was similar but it failed in my testing. If I have a chance I'll look further, but someone else may know in the mean time.
