Each IGMP packet has both an IGMP header and an IP header. Just like ICMP, IGMP does not use a transport layer protocol such as TCP or UDP. What types of IGMP messages are there? The IGMP protocol allows for several kinds of IGMP messages: Membership reports: Devices send these to a ...
Some examples are IGMP (Internet Group Management Protocol) and ICMP (Internet Control Message Protocol) that perform internetworking functions which help show the differences in the TCP/IP and OSI models. How Do the OSI and TCP/IP Models Compare? The upper or top three layers in the OSI ...
The OSI protocol stack works on a hierarchical form, from the hardware physical layer to the software application layer. There are a total of seven layers. Data and information are received by each layer from an upper layer. After the required processing, this layer then passes the information ...

Network layer protocols include IP, the Internet Control Message Protocol (ICMP), the Internet Group Message Protocol (IGMP), and the IPsec suite. 2. The data link layer The data link layer is very similar to the network layer, except the data link layer facilitates data transfer between tw...
The Internet Control Message Protocol (ICMP) is an error reporting protocol that is an integral part of the IP protocol. ICMP communicate control data, information data, and error recovery data across the network. Problems that are less severe than trans

The destination address of an ICMP Request packet is a broadcast address or subnet broadcast address. Attack from packets with invalid TCP flag bits A TCP packet contains six flag bits: URG, ACK, PSH, RST, SYN, and FIN. If the six flag bits are all 1s, the attack is a Christmas tree...
