What is DNS?
Let’s talk about DNS, or Domain Name System. You might have heard the term before, but what exactly is it? At its core, DNS is responsible for translating domain names into IP addresses. But what does that mean? Well, think of it like a phonebook. Just as a phonebook matches names to phone numbers, DNS matches domain names to their corresponding IP addresses.
So why do we need this? Well, it’s much easier for us humans to remember domain names, like google.com or apple.com, than to remember a string of numbers like 172.217.6.46. DNS acts as a directory service, allowing us to access websites and services by using these human-readable domain names, instead of having to remember complex IP addresses.
But DNS does more than just translation. It also helps manage domain names and their associated records, like MX records for email routing. And it supports the resolution of hostnames to IP addresses and vice versa, enabling devices to communicate with each other effectively.
DNS operates using servers, known as DNS servers. These servers store and manage the domain name records and provide responses to DNS queries. DNS configuration includes setting up and managing these servers, as well as managing domain names and their records.
What is DHCP?
Now, let’s turn our attention to DHCP. DHCP stands for Dynamic Host Configuration Protocol and is responsible for assigning and managing IP addresses within a network. It provides automated configuration and allocation of IP addresses, subnet masks, default gateways, and other network parameters to devices, ensuring efficient network connectivity and reducing manual configuration efforts.
