It is very unclear what you want to do.
What's that console/Windows application? Is that something you want to write and use as a monitor for such accesses?
Or is the issue something totally different. E.g. someone accesses your machine's hard disk, e.g. by writing to a shared directory, and you want to see that access somehow? Like the Network tab on Windows 7's Resource Monitor?

Solution 2

Try this code:
using System.Net;

C#

IPAddress[] localIPs = Dns.GetHostAddresses(Dns.GetHostName());
foreach(IPAddress address in localIPs)
   MessageBox.Show(address.ToString());

How can I get only ipv4 address only?

Kuthuparakkal · Answer 2 · 2012-09-14T01:31:00

1.1 Framework:

C#

StringBuilder sb = new StringBuilder();
string strHostName = Dns.GetHostName();
IPHostEntry ipEntry = Dns.GetHostByName(strHostName);
IPAddress[] addr = ipEntry.AddressList;
for (int i = 0; i < addr.Length; i++)
{
    sb.Append(addr[i].ToString());
}
string myip = sb.ToString();

2.0 or later framework

C#

StringBuilder sb = new StringBuilder();
// Get the hostname
string myHost = System.Net.Dns.GetHostName();
System.Net.IPHostEntry myIPs = System.Net.Dns.GetHostEntry(myHost);
foreach(System.Net.IPAddress myIP in myIPs.AddressList)
sb.Append(myIP.ToString());

string myip = sb.ToString();

hi dear

try below code

C#

public void getLocalIPAddress()
{
   try
   {
     string sHostName = Dns.GetHostName();
     IPHostEntry ipE = Dns.GetHostByName(sHostName);
     IPAddress[] IpA = ipE.AddressList;
     for (int i = 0; i < IpA.Length; i++)
     {
         Console.WriteLine("IP Address {0}: {1} ", i, IpA[i].ToString());
     }
   }
   catch (Exception ex)
   {
      MessageBox.Show(ex.Message.ToString(), "getLocalIPAddress");
   }
}

Solution 5

You would have to write your own firewall to do this. You would also need to write a filter driver to insert into the network stack so you can pick out all the inbound traffic and get the addresses you're interested in.

Oh, and you'll probably need to write some heuristics into your "filter" so you can get a better idea of what is and is not "unknown".

Good Luck!

How to write your own firewall ?

Dave Kreskowiak 8-Oct-12 8:06am

That would take an entire book to discuss. That's FAR more information than you're going to get in a couple of forum posts.
