DNS and DHCP Configurations in Linux

 Introduction

        Managing DNS and DHCP are very common tasks for system administrators. In large enterprises, this can be done using complex software and might even be done by separate teams. In smaller networks, you might be the only person behind all networking services. In a case like this, using a simple solution like dnsmasq might be appropriate.
