Hello Everyone,
In this Wireshark lab we focus on IP (Internet Protocol), you can gather important information about the network layer communication between devices.
📌Here are key pieces of information you can obtain:
1)Source and Destination IP Addresses:
Identify the source and destination IP addresses in the IP headers of packets. This information is fundamental for understanding the origin and destination of network traffic.
2)Time-to-Live (TTL):
The TTL field in the IP header represents the number of hops a packet can take before being discarded. Monitoring TTL values helps in detecting routing loops and understanding the path packets take through the network.
3)IP Version:
Check the IP version in the IP header (IPv4 or IPv6). This information is crucial for determining the addressing format used in the communication.
4)Header Length:
The IP header length field indicates the size of the IP header. It is important for correctly parsing the IP header and locating the start of the payload.
5)Type of Service (TOS) or Differentiated Services (DSCP):
TOS or DSCP values in the IP header may indicate the quality of service requested or the priority of the packet in the network.
6)Fragmentation:
IP packets can be fragmented during transit if they exceed the Maximum Transmission Unit (MTU) of a network link. Wireshark can display information about fragmented packets and their reassembly.
7)Identification:
The identification field in the IP header is used for reassembling fragmented packets. It allows packets to be associated with a particular communication stream.
8)Flags:
The IP header flags include the Don’t Fragment (DF) and More Fragments (MF) flags, which indicate whether a packet can be fragmented and if there are more fragments to follow.
9)Checksum:
The IP header contains a checksum field for error detection. Wireshark can help identify corrupted or improperly transmitted packets by checking the integrity of the checksum.
–Analyzing IP traffic with Wireshark is fundamental for understanding the structure and characteristics of network communication. It helps in diagnosing network issues, monitoring traffic patterns, and ensuring the proper functioning of communication protocols.
