The ping command establishes a connection with the other device on the network and should show a result like this.
![]() TCPIP computer networks use both the IP addresses and MAC addresses of connected client devices. While the IP address changes over time, the MAC address of a network adapter always stays the same. There are several reasons you might want to know the MAC address of a remote computer, and its easy to do by using a command line utility such as Command Prompt in Windows. A single device can possess multiple network interfaces and MAC addresses. A laptop computer with Ethernet, Wi-Fi, and Bluetooth connections, for example, has two or sometimes three MAC addresses associated with it, one for each physical network device. Reasons to track down the MAC address of a network device include. To determine the devices manufacturer (first half of the address) and serial number (second half of the address) for service. Its important to note that the second half of the address is not always the serial number, so it might not work for warranty requests. MAC addressing spoofing can be used legitimately to register a home network gateway device with an internet provider. It can also have malicious intent, such as to defeat the MAC address filtering feature to break into the network. It isnt usually possible to look up MAC addresses for devices that are outside a persons physical reach. It often isnt possible to determine the MAC address of a computer from its IP address alone because these two addresses originate from different sources. ![]() However, if the computers are connected to the same TCPIP network, you can determine the MAC address through a technology called ARP ( Address Resolution Protocol ), which is included with TCPIP. Using ARP, each local network interface tracks both the IP address and MAC address for each device it has recently communicated with. Most computers let you see this list of addresses that ARP has collected. In Windows, Linux, and other operating systems, the command line utility arp shows local MAC address information stored in the ARP cache. However, it only works within the small group of computers on a local area network (LAN), not across the internet. ARP is intended to be used by system administrators and is not a typically useful way to track down computers and people on the internet. Get The Address To Change Into A Address For A Cricket Phone How To Find AHere is one example of how to find a MAC address using an IP address. Use a local address, so if your network is 10.0.1.x, then use that number to ping.
