Hi everyone
I need to simulate NSLOOKUP but with asp.net in c# o vb.net, any idea?
I don't need a very complex example, only 2 textbox for the domain and other
for the DNS server, and one button, that's all.
Any help?
Thanks
 
Example from .NET SDK Documentation

try
{
IPAddress hostIPAddress = IPAddress.Parse(IpAddressString);
IPHostEntry hostInfo = Dns.GetHostByAddress(hostIPAddress);
// Get the IP address list that resolves to the host names contained in
// the Alias property.
IPAddress[] address = hostInfo.AddressList;
// Get the alias names of the addresses in the IP address list.
String[] alias = hostInfo.Aliases;

Console.WriteLine("Host name : " + hostInfo.HostName);
Console.WriteLine("\nAliases :");
for(int index=0; index < alias.Length; index++) {
Console.WriteLine(alias[index]);
}
Console.WriteLine("\nIP address list : ");
for(int index=0; index < address.Length; index++) {
Console.WriteLine(address[index]);
}
}
catch(SocketException e)
{
Console.WriteLine("SocketException caught!!!");
Console.WriteLine("Source : " + e.Source);
Console.WriteLine("Message : " + e.Message);
}
catch(FormatException e)
{
Console.WriteLine("FormatException caught!!!");
Console.WriteLine("Source : " + e.Source);
Console.WriteLine("Message : " + e.Message);
}
catch(ArgumentNullException e)
{
Console.WriteLine("ArgumentNullException caught!!!");
Console.WriteLine("Source : " + e.Source);
Console.WriteLine("Message : " + e.Message);
}
catch(Exception e)
{
Console.WriteLine("Exception caught!!!");
Console.WriteLine("Source : " + e.Source);
Console.WriteLine("Message : " + e.Message);
}

In your case just replace console output to your needs.
