I would like to know what does these parts below mean.

What is 0010

What does the 08 00 27 d5... mean

What does the data on the right mean


Solution

  • The 0000:, 0010:… indicates the indexes in your frame in hexadecimal. Since each line contains 16 bytes (10 in hexadecimal), the indexes increase 10 by 10.

    The 08 00 27 d5 … is the content of your Ethernet frame. Byte per bytes. The 6 first bytes are the Ethernet destination address. The 6 next ones, the Ethernet source address. The 2 next ones (08 00) indicates the type of the frame (here IPv4), then there is the content of the IPv4 dataframe.
