65535
Attempted by 295 students.
Show answer & explanation
Correct answer: D
In IPv4, the Total Length field in the header is 16 bits long
A 16-bit field can represent values from 0 to 65,535
So, the maximum possible size of an IPv4 datagram is 65,535 bytes
This includes both the header and data (payload)
In practice, packets are often smaller due to MTU (Maximum Transmission Unit) limits in networks
