In order to use ARP tool open the Command Prompt and typeĪnd you will get a list of all the connected devices on your network along with their physical addresses! The command is useful for viewing the Address Resolution Protocol cache and resolving address resolution problems. The ARP tool allows a user to view and modify Address Resolution Protocol table entries on the local computer. To make ARP efficient, each computer caches IP-to-MAC address mappings to eliminate repetitive ARP broadcast requests. The Address Resolution Protocol (Formerly known as ARP) allows a host to find the MAC address of a node with an IP address on the same physical network when given the node’s IP address. It can be done in certain specific situations, but there is no such universal tool to get the IP from the MAC address. No universal tool to get the IP address from MACĪn end user can not easily determine an IP address given a known MAC address. DHCP Manages network configuration by registering and updating IP addresses and DNS names. Determining IP Address from MAC AddressĬomputers can determine the IP address from MAC address using DHCP and other protocols like Address Resolution Protocol. If you don’t know what a Media Access Control (MAC) address is considered reading this Wikipedia article. Taking into account that it is possible to determine the IP address if you know the MAC address of a computer, those looking for total anonymity should also consider changing their MAC address.
