Packet Hex Dump Ehernet Header Analysis + Challenge - Adorapuff - 07-28-2014

So we have a packet hex dump of an Ethernet frame and we are going to analyze it. Yay!
Here's the hex dump:

1 octet such as 00 = 1 bytes
EtherType -> Protocol Map - http://en.wikipedia.org/wiki/EtherType

Here's a breakdown of a frame:
  • Ethernet Header - 14 bytes
    • Destination Mac Address - 6 bytes
    • Source Mac Address - 6 bytes
    • EtherType - 2 bytes
  • IP Header
  • Protocol Header - TCP, UDP, etc
  • Payload

Breakdown of out packet:
  • Ethernet Header 00 05 73 a0 00 00 e0 69 95 d8 5a 13 86 dd
    • Destination Mac Address - 00:05:73:a0:00:00
    • Source Mac Address - e0:69:95:d8:5a:13
    • Ether-type - 86 dd which when found on the Wikipedia map is IPV6
  • IPV6 Header
    • The 06 7 bytes later tells us the protocol is TCP
  • TCP
  • HTTP

Pretty sure I got it. Would have been more fun if you didn't decode the hexidecimal for us though :3

OK, removed the decoded hex.
