need help on these Networking ethernet Questions

Pick a remote web server or other publicly reachable Internet host and use ping to send some ping messages and check that it sends replies. For example, ping www.bing.com. You should see several replies indicating that the pings reached the remote host and were returned. The figure below shows a successful example. Note that some versions of ping will continue to bounce messages off of a remote server until you tell the program to stop by signaling it with ^C. If your ping test does not succeed then try another server. Launch Wireshark and start a capture of Ethernet frames with a filter of icmp, making sure that enable MAC name resolution is checked. The latter will translate Ethernet (MAC) addresses to provide vendor information. Also check that the Link-layer header type pulldown says Ethernet. When the capture is started, repeat the ping command above. This time, the packets will also be recorded by Wireshark. After the ping command is complete, return to Wireshark and use the menus or buttons to stop the trace.

1) To show your understanding of the Ethernet frame format, draw a figure of the ping message that shows the position and size in bytes of the Ethernet header fields. Your figure can simply show the frame as a long, thin rectangle. The leftmost fields come first in the packet and are sent on the wire first. On this drawing, show the range of the Ethernet header and the Ethernet payload. Add a dashed box at the end to represent the 4-byte checksum; we know it is there even if Wireshark does not show us this field. To work out sizes, observe that when you click on a protocol block in the middle panel (the block itself, not the + expander) then Wireshark will highlight the bytes it corresponds to in the packet in the lower panel and display the length at the bottom of the window. You may also use the overall packet size shown in the Length column or Frame detail block.

2) Each Ethernet frame carries a source and destination address. One of these addresses is that of your computer. It is the source for frames that are sent, and the destination for frames that are received. But what is the other address? Assuming you pinged a remote Internet server, it cannot be the Ethernet address of the remote server because an Ethernet frame is only addressed to go within one LAN. Instead, it will be the Ethernet address of the router or default gateway, such as your AP in the case of 802.11. This is the device that connects your LAN to the rest of the Internet. In contrast, the IP addresses in the IP block of each packet do indicate the overall source and destination endpoints. They are your computer and the remote server. Draw a figure that shows the relative positions of your computer, the router, and the remote server. Label your computer and the router with their Ethernet addresses. Label your computer and the remote server with their IP addresses. Show where the Ethernet and the rest of the Internet fit on the drawing.
