The IP datagram format is described in Table 56 and illustrated in Figure 86. ... Total Length (TL): Specifies the total length of the IP datagram, in bytes. Since this field is 16 bits wide, the maximum length of an IP datagram is 65,535 bytes, though most are much smaller.

This is then encapsulated into the body of an IP message, usually called an IP datagram or IP packet. Encapsulation and formatting of an IP datagram is also sometimes called packaging—again, the implied comparison to an envelope is obvious. ... Figure 85: IP Datagram Encapsulation...

Note: the total_length field in the IP header is 16 bits. that means the max size of of an IP datagram is 65535 bytes. ... When an IP datagram is fragmented, each fragment is treated as a separate datagram.

Note: An IP datagram contains source and destination addresses along with data and a number of fields that define such things as the length of the datagram, the header checksum, and flags that indicate whether the datagram can be (or has been) fragmented.
