What is a DNS Server and Why is it Important?
A DNS server stands for Domain Name System server. It is a type of server that is responsible for translating human-readable domain names, such as www.example.com, into IP addresses, such as 192.168.0.1, that are machine-readable. DNS servers play a crucial role in the functioning of the internet, as they are responsible for mapping domain names to IP addresses.
Without DNS servers, we would need to remember and type in IP addresses to visit websites, which would be highly inconvenient. DNS servers also improve internet performance by caching frequently accessed domain name mappings, reducing the time it takes to access websites.
Another important function of DNS servers is security. DNS servers can help protect against malicious websites and phishing attacks by blocking access to harmful domains or redirecting users to safe ones.
In short, DNS servers are an essential component of the internet infrastructure and play a vital role in maintaining internet performance and security.

What is a DNS Server?
If you are a regular internet user, you might have come across the term DNS or Domain Name System. A DNS server is a network component that translates domain names to IP addresses, making it possible for us to access websites by using easy-to-remember domain names instead of long IP addresses.
In simpler terms, when you type a URL into your web browser, the request is sent to a DNS server to retrieve the IP address associated with that domain name. Once the IP address is obtained, your web browser can establish a connection with the server hosting the website and load the web page for you.
A DNS server acts like a phonebook for the internet, and without it, we would need to memorize long strings of numbers for every website we want to visit.
Most internet service providers (ISPs) provide their customers with a default DNS server, which is used automatically when they connect to the internet. However, there are also public DNS servers available that can be faster, more secure, or provide additional features.
Overall, DNS servers play a crucial role in how we access and use the internet, making it important to understand what they are and how they work.
A Brief Explanation of DNS Servers
DNS, which stands for Domain Name System, is a critical component of the internet infrastructure. Simply put, it is a system that translates human-readable domain names, such as google.com, into machine-readable IP addresses, such as 172.217.12.4
DNS servers are the backbone of this system, which store and manage records of domain names and their corresponding IP addresses. Without DNS servers, users would have to remember IP addresses instead of domain names, making the internet much less user-friendly.
When a user types a domain name into their web browser, the browser sends a request to the local DNS server to translate the domain name into an IP address. If the local DNS server doesn’t have the information, it forwards the request to other DNS servers until it gets the IP address and returns it to the user’s browser.
In essence, DNS servers act as intermediaries between users and the internet, allowing users to access websites and other online services using easy-to-remember domain names instead of confusing IP addresses.
Now that we have a basic understanding of DNS servers, let’s take a look at why it’s essential to know your DNS server on a Mac.
