Network Programming with Go

2 Resource Location and Traffic Routing

To write effective network programs, you need to understand how to use human-readable names to identify nodes on the internet, how those names are translated into addresses for network devices to use, and how traffic makes its way between nodes on the internet, even if they’re on opposite sides of the planet. This chapter covers those topics and more.

We’ll first have a look at how IP addresses identify hosts on a network. Then we’ll discuss routing, or sending traffic between network hosts that aren’t directly connected, and cover some common routing protocols. Finally, we’ll discuss domain name ...
