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

ASP. NET is simple and practical to obtain MAC addresses and IP addresses using DNS, as follows: The following is a reference clip: PrivateVoidButtonIP_Click (object sender, System. EventArgs e) {System. Net. IPAddress [] addressList = Dns. GetHostByName (Dns. GetHostName (). AddressList; If(AddressList. Length> 1) {TextLIP. Text = addressList [0]. ToS

The nemesis packet sending function is used to construct ARP requests and batch processing. All IP addresses and corresponding MAC addresses of the same network segment can be identified within 10 seconds.Batch Processing code: discover. bat@ Echo offSet ip = 0: LoopIf % ip

certain form of link, finally transmitted to the target node. The ARP protocol is responsible for ing IP addresses to MAC addresses for packet movement between these nodes. An example of how IP addresses and MAC addresses are com

The IP address and the MAC address are divided into three types: broadcast address, multicast address, and unicast address. First, FF: FF is undoubtedly a broadcast address. Each ENI is assigned a unique Unicast address when it leaves the factory. The first 24 bits are the ID of the equipment manufacturer, which is allocated by IEEE (Association of Electrical and Electronics Engineers, the last 24 bits are the unique ID specified by the device manufac

· 168 · 100 · 1 to 192 · 168 · 100 · 254.That is to say, the following addresses are all in one CIDR block.192 · 168 · 100 · 1, 192 · 168 · 2... 192 · 168 · 100 · 20... 192 · 168 · 100 · 111... 192 · 168 · 100 · 254 5) number of hosts Number of hosts = 2 binary number of hosts-2 2 is because the host does not include the network address and broadcast address. In this example, the number of binary hosts is 8 bits. Number of hosts = 28-2 = 254 2) over

client receiving service does not need to determine the port number The port number is determined by the Transport layer protocol, so the non-transport protocol can use the same port number, so TCP and UDP can use the same port numberProblem: Now many tools can change the MAC address of the machine, that is, there are many MAC addresses on the network are changed to the same, but there is no communication anomaly or confusion why?Answer: M

there are many ways to obtain a MAC address from an IP address on the Internet. However, due to the relationship between routers, you can only obtain the MAC address of an IP address in the same network segment, later, I learned a doscommand "NBTSTAT". This command can be used to obtain the MAC from different network segments. However, I have tested that some addresses
