For many of us, connecting to the internet is as easy as striking a few keys on your keyboard or tapping on some letters on your smartphone.
We can connect to a seemingly endless amount of internet services within seconds. That's all thanks to DNS.
DNS ensures the internet is not only user-friendly but also works smoothly, loading whatever content we ask for quickly and efficiently.
It's one of the cornerstones of how the internet operates. Without it, we'd be stuck memorizing long lists of numbers (IP addresses) to access the content we want.
If a DNS cannot translate the domain name with the right IP address, you won't be able to access the website you're looking for.
In addition, let's say you've memorized the IP addresses of the websites or services you most frequently visit.
What would happen then if the owners of those IP addresses decide to change them? Suddenly the IP address you've memorized will no longer lead you to the content that you want.
The Domain Name System resolves the names of internet sites with their respective IP addresses adding efficiency and even security in the process.
An authoritative DNS server holds and maintains DNS records.
It is the last server in a DNS lookup chain that responds with the queried DNS record.
An authoritative DNS ultimately allows a web browser with the URL request to reach the IP address needed to access a website or other web resources.
An authoritative DNS domain name server is a definitive source for DNS domain name resolution.
All domains are assigned a unique IP address on the Internet.
When a website address is typed into a browser, like Firenet VPN, the browser response is to convert this URL into the correct IP address for this website.
The web browser starts this process by utilizing an internal cache of recent DNS query results.
This cache is the first place the browser checks (if it has this capability) to find the IP address of the requested domain.
