Hi, I'm still a beginner in learning protocols, I'm trying to understand the above question in order to understand more.

(i). answer = 20 bytes

(ii).

(iii).16.18.20.5

(iv). Ip Data = Ip Packet-IP Header = 40 - 20 = 20 bytes

Application Data = UDP length - UDP Header = 20 bytes- ??? bytes

(v).

Can someone guides me how should I answer part ii, iv and v. ?

I appreciate your guides!
