show all ip addresses on network

I want to quickly search all hosts. I have tried the following methods: 1. Ping, of course, but if you want Program And I don't think the speed is too fast. 2. You can use Winpcap to send an ARP request packet, but the acquisition time is uncertain and the acquisition speed is not too fast. 3. Using the sendarp function, it is too slow to scan 255 hosts and the program cannot respond. So I tried? The sendarp function is called by 55 threads respectiv

External addresses we mentioned when discussing IPX addresses in "Introduction to networks", you should know that the Internal address is used to identify the host, while the External address is used identifies a network. In fact, the IP address also has this function, except that the

This article describes the Python implementation method that obtains all IP addresses based on the host name. Share to everyone for your reference. The implementation methods are as follows: ? 1 2 3 4 5 6 7 #-*-coding:utf-8-*-Import sys, socket result = Socket.getaddrinfo (' www.google.com ', None, 0, socket. SOCK_STREAM) counter = 0 for item in

Network Communication is inseparable from the TCP/IP protocol. In a TCP/IP network, each computer must configure the necessary network to communicate and access resources on the network, some major parameters, such as

In Windows XP, a network card can only be bound with one IP address, which makes it inconvenient for me to access the Internet. This is because when I use a notebook in my unit and dormitory, I need to set an IP address, gateway, and DNS respectively, and reset a network connection. I changed it in the dormitory the ni

Execute shell commands in the program to automatically obtain all online IP addresses and open ports in the LAN (Linux)Preface The question is a bit long. It is actually the following: first, let the Shell command be executed in the program, and then pass the execution result to the variable, so that subsequent transactions can be processed, the second is to use

Article title: Linux network settings tips: how to bind multiple IP addresses to a network card ?. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. The

is that these addresses cannot be routed. If your network is composed of multiple network segments, you cannot use this address range. Now I have discussed the problem of default IP Address Allocation for wireless access points. Next I want to talk about how to avoid these problems. First, I want to point out that som

control panel window. At this point, all the ways to change the IP address are "disconnected", so that other people can do nothing even if they want to modify the IP address. Of course, this method can only be used by cainiao netizens. For "Prawn" Netizens, it is almost the ears of the deaf. Because once a netizen finds "netcpl. the cpl file still has a way to r

Recently, due to the need for a management software for penetrating Internet cafes to restrict vswitches and vrouters. I set 10 IP addresses for the local machine to receive data from hardware.I need to get all the IP addresses of the local machine.Now, you have prepared and

purchase of paid IP, in fact, is not expensive.Method Two: Paid IPBefore the software, account purchase and so on only provide methods, and did not provide specific software and service providers, this time to provide my usual pay-IP buyers, he is not the most bull I do not know, but basically enough for me to use. Use it according to your own usage scenarios. The specific purchase process will not speak,

community member, recommends sending ARP packets to this IP address to detect duplicate IP addresses. All machines with the same IP address are restored to the MAC address. If you are using a security solution, we recommend that you block these MAC

Function for obtaining all interfaces and IP addresses of a Local Machine I have been busy with a program recently. To protect all the IP addresses on my machine, I need to get them.Although there is no arp in IPv6, I always want

set interface address. It should be explained that sin_zero is added to this structure mainly to ensure that the data length of struct sockaddr is the same as that of struct sockaddr_in, so that when using standard functions, you can use a unified data interface. Note that the bzero () function should be used to set all sin_zero to zero. Finally, sin_port and sin_addb must be Network Byte Order ). If "inad

Welcome to the network technology community forum. It is sometimes necessary to interact with 2 million technical staff to enter the Tracking IP address. If your network has problems or you need to change some settings, this is useful. As a network manager, when we solve DHCP faults in Windows, we sometimes need to fin

We have also introduced two DHCP relay faults before. I don't know if you still remember them. If you are not clear about it, You can briefly review it. The DHCP relay fault described here is about the problem that clients of different business types cannot obtain IP addresses of different network segments through relay. DHCP relay failure ◆

One day, the firewall's performance monitoring suddenly experienced a problem, ranging from to every day ~ The number of connections that change between and. Today, the number of connections continues to change around. Due to exceptions, I immediately opened the "connection information" in "Real-time Monitoring" of the firewall and found a port with a large number of abnormal data packets, which are characterized: all the destination
