can someone please help me with this assignment with clear explanation

Every student who has taken a Networks course has to be able to decode a packet from raw hex. This is laborious to do, but very educational. So, here below is a packet sniffed from an Ethernet network. Your job is to decode it and answer the below questions. You can find packet header formats on Wikipedia. You can find hex converters (to decimal and ASCII) online. d4 a9 28 06 f0 43 50 7b 9d e4 db el 08 00 45 00 03 2f 4b 9d 40 00 80 06 62 cc co a8 01 bb 83 f7 03 05 de 92 00 50 62 72 96 9e c8 61 7b 5f 50 18 01 00 c9 cf 00 00 47 45 54 20 2f 7e 6b 63 68 72 69 73 74 65 2f 63 68 72 69 73 74 65 6e 2e 68 74 6d 6c 20 48 54 54 50 2f 31 2e 31 Od Oa 48 6f 73 65 64 75 0d 0a 43 6f 6e 6e 65 63 74 69 6f 6e 3a 20 6b 65 65 70 2d 61 6c 69 76 65 Od Oa 43 61 63 68 65 2d 43 6f 6e 74 72 6f 6c 3a 20 6d 61 78 2d 61 67 65 3d 30 0d 0a 55 70 67 72 61 64 65 2d 49 6e 73 65 63 75 72 65 2d 52 65 71 75 65 73 74 73 3a 20 31 0d 0a 55 73 65 72 2d 41 67 65 6e 74 3a 20 4d 6f 7a 69 6c 6c 61 2f 35 2e 30 20 28 57 69

Explanation / Answer

(a) First 6 bytes in the address are Ethernet Destination address ,Field offset [0-5] and next 6 bytes are Ethernet source address(6-11 bytes). Refer above image.

(b) First 3 bytes of ethernet source address represents vendor of equipment of the source. (6-8 Bytes)

(c) Field offset[12-13] represents protocol type in the ethernet header.

(d) Byte offset 14 represents version of protocol which is 0100

(e) Field offset [26-29] represents Source IP Address and Field Offset[30-33] represents destination ip address.

(f) Transport protocol is Transmission Control Protocol (TCP)

(g) Field offset [ 34-35] represents source and Field offset [36-37] represents destination ports.

(h) Application Protocol is Hypertext Transfer Protocol (HTTP)

(I) It establish a connection with the server and send HTML pages back to the user's browser. In this case getting packets back from http://www.csee.usf.edu/~kchriste/christen.html

(j)

IPv4 header checksum = offset[24-25] = 0x62cc

TCP Checksum = fieldoffset[50-51] = 0xc9cf
