Question

Consider the UDP header 12 03 00 1E A3 10.wht us the total length of UDP

Answer 1

To do any data transmission over the network, it has 3 parts:

1. Udp which is called as UDP header,

2. Destination port where to send the data and

3. part is data which end user has input

UDP header size is depended upon whether end user desktop or laptop uses the ipv4 or ipv6

If end user uses ipv4 It uses 20 bytes and if end user uses ipv6 then it uses 40 bytes as maximum

Further in UDP header is divided in 4 parts each, caries 2 bits total of 16 bits

Here source port is 12.03.

Normally destination port carries 2 bits only, which carries 00 1E.
