This chapter extends the use of Python's socket library with a few third-party libraries. It also discusses some advanced techniques, for example, the asynchronous ayncore module from the Python standard library. This chapter also touches upon various protocols, ranging from an ICMP ping to an IPv6 client/server.

In this chapter, a few useful Python third-party modules have been introduced by some example recipes. For example, the network packet capture library, Scapy, is well known among Python network programmers.

A few recipes have been dedicated to explore the IPv6 utilities in Python including an IPv6 client/server. Some other recipes cover Unix domain sockets.
