For example, in 39th packet, 42 in the Length column represents that the packet size is 42 bits and ‘Who has 192.168.2.1?’ in the Info section represents that the source is enquiring about the device in the network whose IP address is 192.168.2.1.Acunetix Manual Tools is a free suite of penetration testing tools. Wireshark also provides the packet length in bits in the ‘Length’ section and the details about the packet in the ‘Info’ section. For example, when any website is searched in the web browser, it triggers a DNS request, which is sent by the computer to a DNS server in order to get the website's IP address. In 38th packet, Domain Name System (DNS) protocol is mentioned which is used to send a DNS query to a name server to resolve a domain.

In this case, Wireshark provides MAC address of the source device which is inquiring about the device in the network having a specific IP address. For example, in 39th packet, Address Resolution Protocol (ARP) protocol is mentioned which is used to map an IP address to the MAC address of the device that has that IP address. The 'Protocol' column contains information about the network protocol utilised for communication. Similarly, in 38th packet, a2:85:2a:14:5f:d2 represents the MAC address of the source and ‘Broadcast’ in the destination column represents that the message is being broadcasted to the network devices by the source. For example, in 39th packet, 192.168.2.1 and 192.168.2.130 represents the IP address of the source and destination respectively. This data might be in the form of an IP address, a Media Access Control (MAC) address, or any other identification-based information. The 'Source' and 'Destination' columns include source and destination identifying data. For example, in packet number 39 in figure 2, the time 3.832609 represents that the 39th packet is received after 3.832609 seconds from the beginning of packet sniffing. The time column in Wireshark gives a time stamp for a packet that reflects the time after which the packet is received when packet sniffing begins. Most sniffers could only monitor one channel at a moment on a wireless network, however using several wireless interfaces can increase these capabilities. Sniffers may have access to all packets on a wired network or may be constrained by the location of network switches. Both wired and wireless networks can utilise packet sniffers, but the effectiveness of their usage relies on how much of the network they are capable to observe because of network security measures. The next mode is 'filtered,' in which analysers only record packets that include a given set of data items. The first is 'unfiltered,' which means it will record every packet it can and save it for subsequent analysis. Sniffers can be set up in two different ways. Network managers employ packet sniffing tools to track and verify network traffic whereas hackers might use them for illicit activities.

These packets are used by packet sniffers to analyse networks.

In contrast, the nodes designed for packet sniffing deviate from this standard approach and gather all or a specified sample of packets, regardless of their destination address. In most cases, a node ignores a packet that it discovers is directed to another node. A packet's control information is examined by each network device to determine the destination node. Data packets sent over a network go through a number of nodes. Using packet sniffers, data flow is intercepted as it travels across the network and copied to a file. To make sure that packets arrive at their intended location, the control information comprises the IP (Internet Protocol) addresses of the source and the destination, packet sequencing information (such as packet number), and more. As packets intended to be sent to a particular node frequently transit through several nodes in a network and have the possibility to reach at the inaccurate node, the control information is necessary. Along with actual data, the packets include control information to facilitate the transport of packets from transmitter to the receiver.

Depending on the network protocol, these packets have different formats. Data is exchanged among different nodes in a network in the form of compact data chunks known as packets. Although, these networks use the same basic concepts for transmission of data. Modern networks include a combination of physical and wireless connectivity. A stable network connection makes sure that data is sent between these nodes consistently and at a reasonable speed based on the capacity of the network. All of these elements are referred to as nodes in the context of networking. Every network comprises numerous elements, including workstations, servers, networking devices, and more.
