Packages from Scapy

Question

I’m having some doubts I can’t resolve about the scapy, Could you help me please?

Doubts:

1. To declare a package on Scapy I do: pck = IP()/TCP(). With this I can consult the layers of pkt, with for example: pkt[IP] or pkt[0], there arises a doubt:

   • What kind of data is pkt? A dictionary? How does it use a class such as index(in the IP case) or a number?

2. How Scapy treats the "/" of IP()/TCP() so that Python doesn’t understand as the divider?

Answer 1

Here he speaks a little.

1. For the guy tries to give a

print(type(pkt))

But in doc when instance an IP it returns an <IP ... >

2. But with respect to the operator, most likely in the code there was an operator overload, overriding the standard division behavior using python’s Data Model [1] .
