In our day-to-day lives, we take a lot of things for granted. Our body, our friends, water, the food we eat, clothes we wear, IP address of our host, FQDN of our favorite websites, etc. In our ignorance, we forget to consider how our lives would be without them. Let’s discuss the leisure of friends, food, etc sometime later. For now, we’ll limit our thoughts to how DHCP and DNS are managed in AWS, both of which are the backbone to connections among hosts and servers over a network.
