Computer Networks fall into three classes regarding the size, distance and the structure namely: LAN (Local Area Network), MAN (Metropolitan Area Network), WAN (Wide Area Network). Before we discussing about type of network we can discuss about what is a network. We’ll be covering the foll...
ARP防火墙是通过在系统内核层拦截虚假ARP数据包以及主动通告网关本机正确的MAC地址，可以保障数据流向正确，不经过第三者的防火墙。可以保证通讯数据安全、保证网络畅通、保证通讯数据不受第三者控制。包括 拦截ARP攻击、拦截IP冲突、Dos攻击抑制、ARP数据分析等功能。
Network communication protocols.The efficiency of a network is determined by the communication protocols used. The formats and regulations that govern how data is exchanged between networks are formally described by these protocols. This applies to both hardware and software and is a requirement for co...
When you first hear a network geek say to you, "your machine will not be found, of course, because its MAC address is not on the ARP map", you are just too ashamed to find a hole to get into. A more effective and less violent response would be to learn these important terms. ...
ARP(ADDRESS RESOLUTION PROTOCOL) is a network layer protocol which associates the physical hardware address of a network node(commonly known as a MAC ADDRESS) to its ip address. now an ARP creates a table known as ARP CACHE/TABLE that maps ip addresses to the hardware addressess of nodes on...

The computer broadcasts an ARP probe to the network asking “who has <IP address>” with <IP address> replaced the relevant IP address. Every device on the network will see this message as it is a broadcast. Most will ignore it as it’s not aimed at them. But the device that has ...
Layer 1: Physical layer network protocols Interfaces between network medium and devices. Defines optical, electrical, and mechanical characteristics.Though some say the OSI model is now redundant and less significant than the Transmission Control Protocol (TCP)/IP network model, there are still referenc...
Proxy ARP is a method where a device within a network responds to ARP requests for a network address that is not part of that specific network.Key characteristics of Proxy ARP include:Gateway Deployment: Proxy ARP is implemented at the gateway without requiring adjustments to the configurations ...
Network monitoring is the process of continuously observing and analyzing network traffic, performance, and availability to ensure the stability, reliability, and security of a network infrastructure. It involves the use of specialized software and tools to track various metrics, such asbandwidthusage,la...
