Is ip address is a physical address?
No an IP address is considered a logical address. Physical address refers to a MAC address which is burned into ROM on each Ethernet network interface card or NIC.
In theory every NIC card has a unique physical address which denotes its manufacture and its own unique address.
The logical address or IP internet protocol address is used for layer 3 routing between networks and subnets.
ARP stands for Address Resolution Protocol, a network layer protocol used to convert an IP address into a physical address, such as an Ethernet address. A host wishing to obtain a physical address broadcasts an ARP request onto the TCP/IP network. The host on the network that has the IP address in the request then replies with its physical hardware address.
In Windows, you can find out what physical address is assigned to each IP (logical) address by using the following command in the command window: arp - r If a certain IP address doesn't appear in the list, you may first have to force your computer to communicate with that IP address, for example, with the ping command. In Windows, you can find out what physical address is assigned to each IP (logical) address by…
ARP used for resolving mac address from ip address, say one client want to communicate with another and the sender knows only its destination IP address. For communication it requires the physical address of the destination, thus sender uses ARP protocol to resolve the physical address of the destination from ip address by sending arprequest to destination system.
Without a physical address, you will not be able to access a network outside the LAN that you are on. This is simply due to the fact that the computer on another LAN would not know where to forward the requested information. Your IP address work on the Internet Protocol within routers and switches, and associates it finding with your local machine (computer) by way of its mac address (physical address). Notice, your computer does…
