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 not have an IP address, when you log on to the Internet a DHCP server issue you a leased IP address which is associated with your MAC for the duration of time that your computer is log on to the NET. There are quite a few reasons why your computer would not be network operable without a MAC address, this is just one of them.

What does ARPA stand for?
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.
What protocols translates from a numeric IP address to a physical numeric address?
The answer is ARP.
What converts an IP address to its corresponding physical network address?
ARP address resolution protocol
How can you get a physical address from an IP address?
The ISP can link the IP address to the subscriber, but they won't do this for just anyone - it's typically limited to law enforcement agencies.
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.
What is logical address in computer networks?
logical address is called as global address and physical address is called as local address .the ip address,which is used by the user in the network is found to be global for use and it is easily identified in any network .physical address is mac address ,which is stored in the nic card,which is mainly used ,when the system is connected in the network using switch
Why is IP important?
an ip address is like a physical address at your house. it tells information where to go, like youre mail man where to deliver your mail.
How IP addresses are needed to identify computers on a network and what they look like.?
A typical IP address takes the form of 256.256.256.256 - Each IP address is unique - and identifies a single computer connection.
Which situation Address Resolution Protocol used?
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.
Is an IP address sufficient evidence to convict someone of a crime?
No, an IP address alone is not sufficient evidence to convict someone of a crime. Additional evidence is typically needed to establish a connection between the IP address and the individual responsible for the crime.
Is the domain name the internet address of the computer on the internet where the web page is located?
The domain name and the IP address (the physical address of the computer) are both the internet address of the site. The IP is the actual address and the domain name, how it is usually known, is linked to the IP address using a DNS (Domain Name System). IP addresses are assigned by the ISP, the organization that supplies the internet connection. Changing the ISP means changing the IP address. However, the owner of the web site still owns the domain name. If a site is moved, the domain name does not change, but the DNS records (the physical directory listing all the domain names with their corresponding IP addresses) has to be fixed to reflect the new IP address for the Domain Name.
How many IP addresses would be needed to assign a unique IP address to every house in your country?
About 60 Million for me.
