Abstract

This talk is an introduction to the Internet's structure and protocols through fun experiments from the Python perspective.

We'll use Python libraries like Scapy and Twisted to explore:

  • What happens under the hood when you type python.org into your browser bar and hit enter
  • What data you reveal about yourself as you surf the Web
  • How coffee shop Internet access works
  • How to propose marriage on your local network via ARP cache poisoning

By the end of this talk you'll:

  • Understand the core Internet protocols and how design decisions from the early Internet impact us today
  • Have exposure to popular Python networking libraries
  • Ace basic networking interview questions
  • Think sniffing your own wireless traffic is a fun way to spend a Saturday morning
