The method of obtaining the IP address of the server is simple and practical by DNS method, as follows:
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";}}
Another way to
So here's how we fix it:Remove The kernel ' s networking interface rules file so it can regenerated# rm-f/etc/udev/rules.d/70-persistent-net.rulesRestart the VM# rebootUPDATE your interface configuration file# Vi/etc/sysconfig/network-scripts/ifcfg-eth0Remove the MACADDR entry or update it to the new macaddr for the interface (listed in this file:/etc/udev/rules.d/70-pers Istent-net.rules).Remove The UUID entrySave and exit the fileRestart the Networking service# Service Network RestartHappy clo
This article mainly introduces seven methods for JS to obtain Client IP addresses, MAC addresses, and host names. JS itself does not support obtaining IP addresses and other information. This article uses other methods to achieve this, if you need a friend, you can refer to the small program that is engaged in JS (javascript) to obtain the Client
using the API functions provided by the Windows SDK GetAdaptersInfo () can obtain the network card name of all network cards, network card description, network card MAC address, network card IP, network card type and other information, and ip_adapter_info structure storage, Use Getifentry () to obtain the state of the network card, can effectively determine whether the network card communication is normal,
"Life is short, I use Python." The efficiency of Python is partly inseparable from its rich modules. Python has a number of third-party modules that can help us do something and reduce development time.A module named "Netifaces" in the Python PyPI Library is a third-party module written in C. OK:1. Get all the gateways for this machine2. Get all the interface interface (NIC NICs) for this machine3. Get details of the interface specified by the machine, including
Today, I am engaged in JS (javascript) mini-programs for obtaining client IP addresses. I searched the internet and found that many of the current systems and browsers are ineffective and helpless, in Chrome and FireFox, JavaScript scripts such as obtaining IP addresses using ActiveX are rarely obtained. The following code passes all windows and later windows tests and provides the Code:Method 1 (for IE onl
Today in the JS (JavaScript) to obtain the client IP applet, the Internet search, many in the current system and browsers are ineffective, very helpless, in Chrome, Firefox rarely get the direct use of ActiveX access to IP and other JS script. The following code is what I tested on all windowsNT5.0 and above systems, giving the code:
Method one (for IE only and the client's IE allows Acitivex to run, via p
First, we need to log in to the current connected router background:
After logging in, we go to the DHCP client face list to view all the computers currently connected:
Then switch to static ARP binding settings under IP and Mac bindings to see that the right side is space, without binding
To switch to ARP map, you can see the IP
The looks up several methods and, after debugging, is a good way to get a local IP and MAC address. Can be used in this aspect of the functional implementation. The main is to add a system.management reference.
Using System;
Using System.Management;

In a B/S system, we often need to obtain some information about the client, such as IP and MAC, for identity authentication. In ASP. NET, it is easy to get the MAC address of the server, but it is really easy to get the MAC address of the client. The common practice is to call Win32API or directly call the nbtstat comm
