DNS, DHCP, and IP Addressing – Gaining Deeper Knowledge of Red Hat Linux Networking

In this chapter, we are going to dig deeper into networking. We will discuss Internet Protocol (IP) addressing in two ways: static and Dynamic Host Configuration Protocol (DHCP). Static addressing occurs when you set the IP address, such as 192.168.1.10, with a gateway address of 192.168.1.1, whereas with DHCP, the IP information is provided by a DHCP server and the system goes through a handshake mechanism to obtain an IP and the DNS and gateway information on the connected subnet. We will go into more detail about static addressing and DHCP addressing later in this chapter. We will also be setting up a DHCP server to provide IP addressing information to systems on your network both manually and through Ansible Automation.

We are then going to look at how we can find other addresses on the internet through the Dynamic Name System (DNS), which attaches Fully Qualified Domain Names (FQDNs...
