The 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). [8]
This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header. It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header. Both fields are eight bits wide.

In packet-switched computer networks, a jumbogram (portmanteau of jumbo and datagram) is an internet-layer packet exceeding the standard maximum transmission unit (MTU) of the underlying network technology. In contrast, large packets for link-layer technologies are referred to as jumbo frames.
Protocol data units of the OSI model are: [1]. The Layer 4: transport layer PDU is the segment or the datagram. The Layer 3: network layer PDU is the packet. The Layer 2: data link layer PDU is the frame.
Bella Hadid's casting in "Yellowstone" opened up a conversation about the women in Sheridan's series.
Similar headers are used in Usenet messages, and HTTP headers. In a data packet sent via the Internet, the data (payload) are preceded by header information such as the sender's and the recipient's IP addresses, the protocol governing the format of the payload and several other formats. The header's format is specified in the Internet Protocol.
