XmlNodeType Members

Enumeration XmlNodeType (namespace: System.Xml) is used to specify the types of XML node.
 
XmlNodeType members:

• None  --> This is returned by the XmlReader if a Read method has not been called.
• Element  --> An element (for example, ).
• Attribute --> An attribute (for example, id='123' ).
• Text  --> The text content of a node.
• CDATA --> A CDATA section (for example, )
• EntityReference --> A reference to an entity (for example, # ).
• Entity  --> An entity declaration (for example, ).
• ProcessingInstruction --> A processing instruction (for example, )
• Comment  --> A comment (for example, )
• Document  --> A document object that, as the root of the document tree, provides access to the entire XML document.
• DocumentType --> for example,
• Notation  --> for example,
• Whitespace  --> White space between markup
• SignificantWhitespace  --> White space between markup in a mixed content model or white space within the xml:space="preserve" scope
• EndElement  --> for example,
• EndEntity 
  
• XmlDeclaration  --> for example,

Check IP Address Type

Idea:
- display all IP addresses
- inspect it one by one, whether:
  - it is IPv4
  - it is IPv6
     - it is loopback address
     - it is link local
     - it is multicast
     - it is site local
     - it is teredo

Resolving Hostname

I know, it is kind of lame. But I'll post it anyway.

using System;                   // for String and Console
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;               // for Dns, IpHostEntry, IPAddress
using System.Net.Sockets;       // for SocketException

    class Program
    {
        static void PrintHostInfo(string host)
        {
            try
            {
                IPHostEntry hostInfo;

                hostInfo = Dns.GetHostEntry(host);  //karena Dns.resolve sudah obsolete 
                //(baca dokumentasi .NET)

                //display the primary hostname
                Console.WriteLine("\tCanonical Name: " + hostInfo.HostName);

                //display list of IP adresses for this host
                Console.WriteLine("\tIP Addresses: ");
                foreach (IPAddress ip in hostInfo.AddressList)
                {
                    Console.WriteLine("\t\t{0}", ip.ToString());
                }

                Console.WriteLine();

                //display list of all aliases for this host
                Console.WriteLine("\tAliases: ");
                foreach (String alias in hostInfo.Aliases)

                }
            }
            catch (Exception) 
            {

                Console.WriteLine("Local host");
                Console.WriteLine("\tHost name: {0}",LocalHostName);

                PrintHostInfo(LocalHostName);                
            }
