C# IPHostEntry Cache???
-
Here is one of the coolest few lines of code to perform a NSLookUp. Simply enter an IP in textBox1, click a button and the domain name translates in textBox2 (providing your workstation is on a WAN. Q. How could we build a 'cache' to capture redundant IP's/Domain's to add lookup performance??? Q. How could we add our own know IP's/Domain's to this 'cache' ??? (Because NOT every IP will resolve) Preferably the code would check our personal 'cache' first before looking on the Internet or elsewhere..... public void ButtonLookupDomain_Click(object sender, EventArgs ea) { IPHostEntry IP = Dns.Resolve(textBox1.Text); txtBox2.Text = IP.HostName; }

}Excellent, clean and simple coding. I like it so far... The more I study windows DNS, I realize my goal is to create my own 'hosts' file. I can write to it and IPHostEntry can read from it instead of the 'hashtable' you've so kindly shared. Q. How can I create my own 'hosts' file in place of the 'hashtable' example??? Thank You.....
