DNS Servers Uncovered

Published Categorized as Uncategorized

In the vast realm of the Internet, where humans traverse through websites effortlessly, the Domain Name System (DNS) plays the role of an unsung hero, akin to a sophisticated phone directory. Instead of grappling with complex numeric addresses like, humans benefit from DNS by converting user-friendly names, such as www.forestvpn.com, into these numerical IP addresses.

The Human-Computer Language Barrier

Numbers are the language of computers, but they leave humans floundering in a sea of forgetfulness. Imagine memorizing the IP address just to reach Google. Fortunately, DNS acts as the translator, saving us from the mental gymnastics of recalling endless strings of numbers.

While DNS resolves the memory hurdle, there’s a twist. To decipher which IP address aligns with a particular name, you must beckon a DNS server. Typically, your default choice is your Internet Service Provider’s (ISP) DNS server, unveiling a subtle trade-off between convenience and privacy.

Unveiling DNS Caching

DNS caching, a silent virtuoso, temporarily stores records of recently visited domain names. This caching dance eliminates the need for incessant DNS queries, expediting the retrieval of your desired websites.

  • Browser DNS Caching: This waltz captures recent queries on browsers like Google Chrome or Firefox.
  • Operating System Level DNS Caching: The operating system, whether macOS, Windows, or Linux, joins the dance of caching for swift access.

Demystifying the DNS Dance

How does DNS orchestrate this symphony?

Step 1: Initiating the Query

In the quest to visit a website like google.com, your device, acting as the virtuoso, seeks the IP address. A DNS query is born, conducted by a DNS client, often a web browser like Chrome.

Step 2: Recursive Resolvers & the Four-Server Ballet

A recursive DNS server, the first ballet dancer, enters the stage. It consults root servers, TLD nameservers, and authoritative nameservers in a seamless performance, unraveling the IP address with breathtaking speed.

  • DNS Recursor: The initial query stop, holding cached data or facilitating new requests.
  • Root Nameserver: Directs towards TLD nameservers.
  • Top-Level Domain (TLD) Nameserver: Holds information for domain extensions.
  • Authoritative Nameserver: The final act, presenting the IP address with authority.

The Enigma of DNS Resolver

In this labyrinth of DNS, the DNS resolver, akin to a wise sage, bridges the gap between the DNS client and nameservers. It commences a quest for the IP address by scanning its local cache, delivering instant resolution if the website is a familiar guest.

Navigating DNS Queries

Different strokes for different queries

Recursive Query

The DNS client embarks on a quest, tracing the answer through root servers to authoritative nameservers.

Iterative Query

Here, the DNS resolver imparts knowledge to the client, guiding it to root or authoritative servers for the answer.

Non-Recursive Query

An omniscient resolver already cradles the answer, eliminating the need for additional queries.

A Peek into DNS Lookup

  1. You whisper a website’s name into your browser.
  2. The DNS recursive resolver picks up the subtle murmur.
  3. A journey to root servers begins.
  4. TLD nameservers join the expedition.
  5. The authoritative nameserver reveals the IP address.
  6. The resolver unveils the website’s IP address to your eager browser.
