We have spent quite a bit of effort working with Scapy in this chapter. This is partially due to how highly I personally think of the tool. I hope you agree with me that Scapy is a great tool to keep in your toolset as a network engineer. The best part about Scapy is that it is constantly being developed with an engaged community of users.
I would highly recommend at least going through the Scapy tutorial at http://scapy.readthedocs.io/en/latest/usage.html#interactive-tutorial, as well as any of the documentation that is of interest to you.
