Local Area Network is a computer network where computers in the same location or group are connected together and shares common communication lines. Local Area Network is mainly expressed as LAN which is a very popular term in computer network and IT. LAN Components LAN will have very simple topology...
MAC Address is used to identify a Network Interface Card uniquely in a layer 2 network. This address is used to transfer files between default gateway and host or computer. In this tutorial we will learn how to find a MAC address from command-line or GUI in operating systems like...
Network switches or Layer 2 technology Ethernet protocol uses MAC addresses in order to transfer frames between systems. MAC addresses are 48 bit value. This 48 bit value contains the device manufacturer ID as the first 24 bit. In this tutorial we will learn how to look, search and find...
Address Resolution Protocol (ARP) is auxiliary protocol used by Internet Protocol (IP). ARP is defined with RFC826 and gained main stream over computer networks. ARP is used to resolve IP address with MAC or hardware address of the network interface. As we know MAC address is used to identify nodes...
Netstat is used to display active TCP connections and related listening ports in the computer or system. Actually, there are more features provided by netstat like display statistics about network stack protocols, IPv4, IPv6, TCP, UDP etc. Syntax Syntax of the netstat command is like below. Simply we can use the...
Network scanning is one of the steps of penetration testing. There are different and popular tools to scan network line masscan, nmap etc. Arp-scan is a tool specifically designed to scan network with layer 2 or mac or Ethernet arp packets. Install We can install arp-scan tool with the following...
There are a lot of tools for network trouble shooting and debugging. Arping is one of them which only pings same network hosts. So what makes arping special is it uses network layer arp packets. This works on mac protocol. It is useful especially to find hosts those do not...
Mac Address is a network address used to layer 2 network traffic. The communication is done between network nodes with mac address. It is important part of the computer networking. In this tutorial we will look different ways to get mac address practically. Getmac Command Getmac command is simple command...
Nmap is very useful tool. I is used by penetration testers mainly but from operation perspective it is used by system administrators too. Nmap have a lot of different features. Mac related feature can be used to get mac addressees of the hosts in the same network segment. I can...
