Each Ethernet device has a unique MAC address at the factory. Why do I need to assign an IP address to each host? In other words, each host is assigned a unique IP address. Why should we embed a unique MAC address in the production of network devices (such as network adapters, hubs, routers, etc? The main reasons are a

Each Ethernet device has a unique MAC address at the factory, why do I need to assign an IP address to each host? or if each host is assigned a unique IP address, why should a unique MAC address be embedded in the production of a network device (such as a NIC, hub, router, etc)? There are several main reasons for this

Many companies need to bind IP-MAC addresses for security reasons. IP-MAC bindings can be implemented in a variety of ways, and in this article I'll show you how the switches are Ip-mac bound.Cisco 2950#进入配置模式Switch#config Termina

Here to share with you about the bulk of the IP address and MAC address methods, in the network management, IP address theft often occurs, not only the normal use of the network, but also because the stolen address often has a higher authority, Therefore, the user has caused a lot of economic losses and potential security risks. Therefore, in order to prevent the

There may not be only one NIC on a machine, but each NIC has only one MAC address, and each network card may be configured with multiple IP addresses; As in the ordinary notebook computer, there will be wireless network card and wired network card (network interface) Two; therefore, if you want to obtain all the network card IP and

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

JS obtains the Client IP address, MAC, and host name in seven ways. Today, I am engaged in JS (javascript) mini-programs for obtaining client IP addresses.
