This chapter discussed Go code for programming web clients and web servers as well as creating a website in Go! You also learned about the http.Response, the http.Request, and the http.Transport structures that allow you to define the parameters of an HTTP connection.

Additionally, you learned how to get the network configuration of a Unix machine, using Go code, how to perform DNS lookups in a Go program, including getting the NS and MX records of a domain.

Finally, we talked about Wireshark and tshark, which are two very popular utilities that allow you to capture and, most importantly, analyze network traffic. At the beginning of this chapter, we also mentioned the nc(1) utility.

In the final chapter of this book, we will continue our discussion of network programming in Go. However, this time, we will present lower-level Go code that allows you to develop TCP clients and servers as well as UDP client and server processes. Additionally, you will learn about creating RCP clients and servers. I hope you'll enjoy it!
