Chapter 5

Configuring TCP/IP Network Services and IPv4 Addressing (Tasks)

TCP/IP network administration evolves in two stages. The first stage is to assemble the hardware. Then, you configure the daemons, files, and services that implement the TCP/IP protocol.

This chapter explains how to configure TCP/IP on a network that implements IPv4 addressing and services.

Note - Many of the tasks in this chapter apply to both IPv4-only and IPv6-enabled networks. Where configuration tasks differ between the two addressing formats, the IPv4 configuration steps are in this chapter. The tasks in this chapter then cross reference the equivalent IPv6 tasks in Chapter 7, Enabling IPv6 on a Network (Tasks).
