Annotate the printout 3 to explain your answer. Whenever possible, when answering a question you should hand in a printout of the packet(s) within the trace that you used to answer the question asked. Note that the contents of the Ethernet frame (header as well as payload) are displayed in the packet contents window.Īnswer the following questions, based on the contents of the Ethernet frame containing the HTTP GET message. Expand the Ethernet II information in the packet details window. (Recall that the HTTP GET message is carried inside of a TCP segment, which is carried inside of an IP datagram, which is carried inside of an Ethernet frame reread section 1.5.2 in the text if you find this encapsulation a bit confusing). Select the Ethernet frame containing the HTTP GET message.

In order to answer the following questions, you’ll need to look into the packet details and packet contents windows (the middle and lower display windows in Wireshark). You should now see an Wireshark window that looks like: To have Wireshark do this, select Analyze->Enabled Protocols. So let’s change Wireshark’s “listing of captured packets” window so that it shows information only about protocols below IP. Since this lab is about Ethernet and ARP, we’re not interested in IP or higher-layer protocols. You should see a screen that looks something like this (where packet 4 in the screen shot below contains the HTTP GET message) First, find the packet numbers (the leftmost column in the upper Wireshark window) of the HTTP GET message that was sent from your computer to gaia.cs., as well as the beginning of the HTTP response message sent to your computer by gaia.cs. You can then use this trace file to answer the questions below.

Once you have downloaded the trace, you can load it into Wireshark and view the trace using the File pull down menu, choosing Open, and then selecting the ethernet-ethereal-trace-1 trace file.

The traces in this zip file were collected by Wireshark running on one of the author’s computers, while performing the steps indicated in the Wireshark lab.

If you are unable to run Wireshark live on a computer, you can download the zip file and extract the file ethernet–ethereal-trace-1.

RFC 826 ( ) contains the gory details of the ARP protocol, which is used by an IP device to determine the IP address of a remote interface whose Ethernet address is known.ġ. Before beginning this lab, you’ll probably want to review sections 6.4.1 (Link-layer addressing and ARP) and 6.4.2 (Ethernet) in the text 1. A RIR is a nonprofit organization that allocates IPv4, IPv6 and ASN (Autonomous System Numbers).In this lab, we’ll investigate the Ethernet protocol and the ARP protocol. The answer is simple, from one or more RIRs (Regional Internet Registry). I hear you are asking “Where does one of the API get geolocation of an IP address from?”. When you are googling for ' What is my IP address?', It probably takes you to a site which is using that kind of API.

There are many free services available on the internet as well as commercial ones which provide some sort of an API (Application Programing Interface) to their clients. With help of IP geolocation, we can find geographic location of an IP address. Especially when we do network forensic analysis which aims to detect attack patterns and identify attackers. There are times when we need to trace an IP address back to its origin (Country, City, AS Number etc.).
