获取服务器的IP地址方法以DNS法较为简单实用，如下：
private void ButtonIP_Click(object sender, System.EventArgs e)
{ System.Net.IPAddress[] addressList = Dns.GetHostByName(Dns.GetHostName()).AddressList;
if ( addressList.Length>1)
{ TextLIP.Text = addressList[0].ToString();
TextSIP.Text = addressList[1].ToString();
}
else

{
TextLIP.Text = addressList[0].ToString();
TextSIP.Text = "没有可用的连接";
}
}

获取服务器的IP地址与MAC地址另一方法如下：
using System.Management;

string stringMAC = "";
string stringIP = "";
ManagementClass MC = new ManagementClass "Win32_NetworkAdapterConfiguration");
ManagementObjectCollection MOC= MC.GetInstances();

foreach(ManagementObject MO in MOC)
{
if ((bool)MO["IPEnabled"] == true)
{
stringMAC += MO["MACAddress"].ToString();
TextMAC.Text = stringMAC.ToString();
string[] IPAddresses = (string[]) MO["IPAddress"];
if(IPAddresses.Length > 0)
stringIP = IPAddresses[0];
TextIP.Text = stringIP.ToString();
}
}

获取客户端本机的IP地址相当简易，方法如下：

using System.Net;

TextIP.Text=Page.Request.UserHostAddress;
