Why do we need IP address in LAN?

The IP address is used to uniquely identify a host or computer on the LAN. You should avoid giving two or more computers the same IP address by using the range of IP addresses that are reserved for private, local area networks; this range of IP addresses usually begins with the octets 192.168.

Why the computers are need of an IP address to be connected?

Just like homes need mailing addresses to receive mail, Internet-connected devices need an IP address to receive messages. When a computer sends a message to another computer, it must specify the recipient’s IP address and also include its own IP address so that the second computer can reply.

What is the purpose of IP address?

The purpose of an IP address is to handle the connection between devices that send and receive information across a network. The IP address uniquely identifies every device on the internet; without one, there’s no way to contact them.

What is an IP address and what is its use?

An Internet Protocol (IP) address is used to connect to the Internet and identify devices so that computers, like desktops, mobile devices, and servers can communicate with each other.

What is IP address of LAN?

LAN IP address is the address given to your host within your local area network, while your WAN IP would be the address given to your routers interface that is connected to the internet, usually at your point of demarcation between you and your ISP.

What is an IP address for dummies?

Put simply, an IP address (short for Internet Protocol address) is a unique identifier for your machine. Computers have them, but so do tablets and smartphones. And, just like a fingerprint or a snowflake, no two IP addresses are exactly the same.

Do I need an IP address to communicate with a LAN?

Technically you don’t need an IP address to communicate within a LAN. In fact, when the actual communication takes place IP addresses are only used for looking up MAC addresses and the device won’t send anything out with an IP address on it except under specific circumstances.

Why do computers on a LAN communicate using a MAC address?

Answer Wiki. Computers on a LAN actually do communicate based on MAC addresses. Every packet that goes over Ethernet uses a MAC address. The reason why TCP/IP is used for higher-level communication (Layer 3 in the OSI model) is because it’s a standard that’s universally accessible and also routable between autonomous networks.

Why do we still use IP addresses when using Layer 2?

The reason IP addresses are still used even when layer 2 is the most relevant layer, is because software is designed to use layer 3 addresses. Still, when you connect to a device on the same network segment, your computer’s not sending “to” an IP address, it’s looking on its own ARP table to convert that IP address to the
