WebPackets in the IPv4 layer are called datagrams. A datagram is a variable-length packet consisting of two parts: header and data. The header is 20 to 60 bytes in length and contains information essential to routing and delivery. It is customary in TCP/IP to show the header in 4-byte sections. WebThe header of an IPv4 packet is between 20 and 24 bytes long and the header of an IPv6 packet is 40 bytes. The maximum size of an IP packet (total) is 2^16 - 1 bytes.

WebThe minimum length is 8 bytes, the length of the header. The field size sets a theoretical limit of 65,535 bytes (8-byte header + 65,527 bytes of data) for a UDP datagram. However the actual limit for the data length, which is imposed by the underlying IPv4 protocol, is 65,507 bytes (65,535 bytes − 8-byte UDP header − 20-byte IP header). WebThe total length field represents the total length of the datagram, including both the header and the payload. The value of the total length field is 100 bytes.
