In this lesson, we’ll walk through each field in the IPv4 header, explain what each field is for, and show you an example of what an actual IPv4 packet looks like. It serves as an instruction manual for routers. The number of header fields is twelve and the length of the header field is twenty. Version will be value 4 – we are primary using IPv4 Header Length – header is at least 20 bytes, excluding the options. The default size is 20 bytes and it can be as large as 60 bytes depending on the size of Options field. IPv4 supportsVLSM (Virtual Length Subnet Mask). The Flags field is used to enable fragmentation and indicate whether more fragments follow. . 4 service bits, One IPv4 option is the Record Route option, in which routers are to insert their own IPv4 address into the IPv4 header option area.
