How to Finding a Specific Computer from an IP address on a Network? - GeeksforGeeks (2024)

Why is the IP address called a "logical" address, and the MAC address is called a "physical" address?

Let us try to deeply understand, why IP address is known as "Logical" while, MAC Address is known as "Physical" address. The IP address and the MAC address are both used for addressing and identifying devices on a computer network, but they serve different purposes and operate at different levels of the network stack. An IP address is a logical add

IP address as logical address and MAC address as Physical address

Overview :IP addresses and MAC addresses are essential for data communication. Assume there are two networks. The first network has three devices: A, B, C and the second network has three devices: X, Y, Z. If a device A from the first network wishes to send data to a device Y in the second network, it must first determine where Y is located in the

How to Find Network IP Address of Computer Using Computer Name?

Answer: By using the command "ping" followed by the computer name in the command prompt or terminal.To find the network IP address of a computer using its computer name: Open Command Prompt or Terminal Begin by opening the Command Prompt (Windows) or Terminal (macOS/Linux) on your computer. Use the Ping Command Type "ping" followed by the computer

Difference Between Network Address Translation (NAT) and Port Address Translation (PAT)

In the world of networking, most of the uses of IP addresses are important due to the limited availability of IPv4 addresses which is a part of network address translation. Two technologies that have been developed to address this problem are Network Address Translation and Port Address Translation. These technologies not only help to keep IP addre

Why Star network is More Efficient in Network Fault Tolerance in Place of Bus Network?

Answer: Star networks offer better fault tolerance than bus networks because a single point of failure in a star network (the central hub) affects only the connected device, while a fault in a bus network can disrupt communication for all devices on the bus.Advantages of Star Topology Over Bus Topology Individual Connection Points: In a star networ

Basic Network Attacks in Computer Network

Many people rely on the Internet for many of their professional, social and personal activities. But there are also people who attempt to damage our Internet-connected computers, violate our privacy and render inoperable the Internet services.

MAC Address and Random MAC Address

MAC Addresses are the address which are specified by the Manufacturer.MAC address help in communicating with the devices with communicating with other devices over the network. They are 12 digit hexadecimal numbers in which first three set bits specify the manufacturer of the device and last 3 specify the specific device. Random MAC Address They ar

Why Do We Need IP Address if We Have Already MAC Address?

Answer: The network allots an IP address to every connected device making sure that every device can be identified separately within the network. Each device is identified by its MAC address, which cannot be shared by two devices. The MAC address is assigned by the embedded Network Interface Card (NIC) of each device and cannot be altered once set.

How do You Calculate the Subnet Address from an IP Address and Subnet Mask?

Answer: To calculate the subnet address from an IP address and subnet mask we first convert both into its binary form and perform the bitwise AND operation between IP address and subnet mask.Subnet MaskThe subnet mask of a network is the number in which all the network bits are set to 1 and all host bits are set to 0. Subnet ID or Subnet AddressThe

What is Physical Address and Logical Address in Networking?

A physical address is a unique identifier given to network interfaces for communication over a physical network segment. A logical address is a unique address assigned to each networked device toidentify its location and enable routing. In this article, we will discuss Physical Address and Logical Address. What is a Physical Address?The physical a

Difference Between MAC Address and IP Address

Both MAC Address and IP Address are used to uniquely define a device on the internet. NIC Card’s Manufacturer provides the MAC Address, on the other hand, the Internet Service Provider provides the IP Address. In this article, we will learn about MAC Addresses, IP Addresses, and their differences. What is MAC Address?MAC, or Media Access Control is

Finding DBA from given IP address

Direct Broadcast Address (DBA): Two addresses are subtracted from the number of hosts in each network because one is used for Net Id and other one is used for DBA of the network. In this article we are going to discuss how to find out DBA of a network if a IP address is given. Following is the procedure of finding it. Procedure: First we need to re

Finding IP address of a URL in Java

Prerequisite: InetAddressgetByName() : Returns the InetAddress of the given host. If the host is a literal IP address, then only its validity is checked. Fetches public IP Address of the host specified. It takes the host as an argument and returns the corresponding IP address. Examples: Input : www.google.com Output : 216.58.199.164 Input : localho

Types of Network Address Translation (NAT)

Prerequisite - Network address translation (NAT) Network Address Translation (NAT) is a process in which one or more local IP address is translated into one or more Global IP address and vice versa in order to provide Internet access to the local hosts. NAT generally operates on a router or firewall. Network address translation (NAT) working - Gene

Difference Between Network Address Translation and Domain Name System

NAT stands for Network Address Translation. NAT is a technique used to connect networks together, it is typically used when a device on a private network wants to communicate with a device on a public network, such as the internet. NAT operates on a router, which is responsible for replacing the private IP addresses of devices in a local network wi

What is the valid range of a Class A network address?

Let us know what an IP address is first, if you already know, skip this section. IP (Internet Protocol): It is one of the fundamental protocols in order to have communications on the Internet. IP describes how the information is addressed, routed by networking devices. An IP address is a number identifying of a computer or another device on the Int

What is a Network Address?

A computer network is a group of interconnected computers that share common or different resources provided on or by network nodes. This sharing or communication between the machines is governed by some set of rules or network protocols. These computers or machines are identified by network addresses and may have hostnames. What is a Network Addres

Network Address Translation (NAT)

One public IP address is needed to access the Internet, but we can use a private IP address in our private network. The idea of NAT is to allow multiple devices to access the Internet through a single public address. To achieve this, a private IP address must be translated into a public IP address. What is Network Address Translation(NAT)?Network A

Finding Network ID of a Subnet (using Subnet Mask)

In order to find network id (NID) of a Subnet, one must be fully acquainted with the Subnet mask. Subnet Mask: It is used to find which IP address belongs to which Subnet. It is a 32 bit number, containing 0's and 1's. Here network id part and Subnet ID part is represented by all 1's and host ID part is represented by all 0's. Example: If Network i

Java program to find IP address of your computer

An IP(Internet Protocol) address is an identifier assigned to each computer and another device (e.g., router, mobile, etc) connected to a TCP/IP network that is used to locate and identify the node in communication with other nodes on the network. IP addresses are usually written and displayed in human-readable notation such as 192.168.1.35 in IPv4
