What Is DNS and How Does It Work?

By David McKinney 8 May, 2023 2 mins read

A server domain is an internet address that identifies the web site. There are many website names available on the web. These include those in education, commerce, government and entertainment.

As soon as you enter a domain in your browser, your computer will match it with the IP address needed to communicate and locate that website. DNS (Domain Name System) maps alphabetic domains to IP addresses, just like in a phonebook.

DNS is a database that uses the client-server system. Name servers are the servers that store information about domains and their IP addresses.

How Does DNS Work

The first step in the DNS process is for a computer to ask a specialized computer, called a root server, what IP addresses are associated with each Top Level Domain. Essentially, each domain contains its own set registries. These registries are then stored on a computer known as the root server.

Once the root server knows what TLD you are looking for, it sends your request to a Domain Name Resolver, which is a computer located within a service provider or organization. These resolvers are experts at locating the registries in each domain as well as translating the domain name to an IP address.

The type of record a DNS request must contain depends on the domain, and what the resolution needs. The A record contains the IP of the domain. CNAME records and TXT records can also be used as aliases or to send the query to a different DNS server.

These records can be defined in a database, also known as a zone file. The zones in the DNS store information about each domain and its corresponding IP addresses, as well as other related information such as DNS cache, time to live (TTL), etc.

The recursive DNS server receives the query and makes it a series of requests until it reaches the authoritative DNS name server for that domain. The recursive DNS then returns an IP address to either the client server.

There are two types of authoritative name servers in the DNS - primary and secondary. The primary DNS server is the one that holds copies of the zone files and all the records for the zone. Secondary DNS servers only come into play when the primary DNS server fails or if it is unavailable.

Authoritative name servers are the final authority on all of the names and IP addresses in a domain or zone. They are also able to change the IP addresses of the domains or zones they manage, making them an essential part of managing and maintaining the DNS on the network.

The recursive DNS server makes the requests until it reaches the authoritative DNS nameserver for the domain or zone. The recursive DNS servers will make queries to other DNS nameservers if the authoritative DNS nameserver cannot provide the information it requires. The recursive DNS service can also return just the IP address. It is usually the fastest method to obtain the IP address you want from a DNS server. This is also the default setting for most DNS services.

FAQ

What is a "static website"?

A static website can be hosted anywhere, including GitHub Pages, Amazon S3, Google Cloud Storage, Windows Azure Blob storage, Rackspace Cloud Files, Dreamhost, Media Temple, and others. You can also deploy static sites to any platform that uses PHP, such WordPress, Drupal Joomla! Magento PrestaShop.

Static web pages are generally easier to maintain since they don't constantly send requests back-and-forth between servers. A static web page loads faster as there is no need to forward requests back and forth among servers. Because of this, static web pages are often more suitable for smaller businesses that don’t have the resources or time necessary to manage a website.

HTML stands for HyperText Markup Language. You can think of it as writing a recipe. You'd list the ingredients, instructions, along with directions. HTML is a way to tell a computer which parts are bold, underlined, italicized or linked to other parts of the document. It's the language of documents.
