Understanding Domains:
What They Are and How
They Work

The domain name, in a URL (Uniform Resource Locator), comes immediately after the protocol (like ‘http://' or 'https://')." For instance, in the URL format, it says, "http://www.example.com/page." This positioning is crucial for proper web address interpretation and routing. The domain name appears before any additional path specifications or resource identifiers, serving as the primary navigational component that directs users to the appropriate web server. Now that you​ have understood ‘domain name, what is it? ', let’s move on to its functioning.

Domain names help people easily find websites by translating human-readable web addresses into computer-recognizable network locations through four key methods. This system operates through four primary mechanisms:

Domain Name Registration

Domain registration starts with authorized registrars communicating with governing bodies like ICANN (Internet Corporation for Assigned Names and Numbers). When registering a domain, you pick a name you want to use with the appropriate top-level domain extension. To register, you must first provide contact information (such as name, phone number, and email address) and agree to terms of service plus periodic renewal obligations to retain domain ownership.

DNS (Domain Name System)

The domain name system is a network of distributed databases that provides basic directory services for the Internet. This sophisticated system keeps track of domain names and the corresponding IP addresses to which they resolve so that we communication between human-readable domain names and machine-readable IP addresses. Each of the servers worldwide that make up the DNS infrastructure partake in processing domain name queries, working together.

IP Address Resolution

When users do a domain name search in their web browser, the system starts its resolution process. When the browser requests a URL, the DNS server is asked to search its database to find the corresponding IP address. Suppose the initial DNS server cannot find the IP address. In this case, it forwards the query to other authoritative DNS servers that will return the correct IP address to the requesting device.

Website Retrieval

If the IP address is successfully resolved, the web browser starts a connection to the web server associated with that IP address. The server processes incoming requests, and the website content requested is sent back to the user browser for rendering and display.

Example of How Domain Works

A complex but fast process begins when you type 'www.google.com' into your browser. First, your request goes to a DNS resolver (e.g., provided by your ISP). If the resolver has not cached the IP address, it contacts the root nameservers (.), which tell it where to go for the top-level domain servers (.com). Then, these servers point to Google’s authoritative nameservers.

When it tries to contact Google.com, Google’s name servers respond with the correct IP address, for example, 142.250.190.78. The current IP address is Google's web servers containing the site. Based on this IP address, your browser uses it to make a TCP connection and to send an HTTP request. When you make this request, Google's servers take it and send back the webpage content to your browser to render.

When you type in a domain name like 'google.com,' the DNS resolution process from domain name to IP address takes place in milliseconds, as there is a significant amount of caching at all levels and as DNS infrastructure is distributed.

Domain names consist of several distinct components, each serving a specific purpose in the hierarchical structure of internet addressing:

Subdomain

Subdomains are optional at the beginning of the main domain name for organizational subdivision in the website's structure. For example, in "blog.example.com," "blog" is the subdomain allowing content categorization and independent resource management.

Second-level Domain (SLD)

The second-level domain is the main identifier of the domain name structure. It’s usually the name or brand identity of the organization, where “example.com” is made up of the example that stands for the second-level domain and is recognized from the website.

Top-Level Domain (TLD)

The top-level domain is the domain name's rightmost segment that indicates the domain's category. There are several types of TLD, with different purposes and requirements in the domain name system.

The domain name system incorporates several distinct categories of top-level domains, each designed for specific purposes:

Generic Top-Level Domains (gTLDs)

gTLDs are the most widely recognized gTLDs for general purposes, with .com, .org, and .net being the most common domain extensions. Anyone and everyone can register under these extensions, with no specific registration restrictions.

• .com: Initially for commercial entities, now unrestricted
• .org: Originally for non-profit organizations
• .net: Initially, for network infrastructure providers
• .edu: Restricted to accredited educational institutions
• .gov: Exclusively for U.S. government entities
• .mil: Reserved for U.S. military institutions

Country Code Top-Level Domains (ccTLDs)

These domain extensions correspond to specific geographic regions or countries, such as .uk for the United Kingdom or .au for Australia. ccTLDs often carry specific registration requirements for geographical presence or business operations within the designated region.

• .uk (United Kingdom)
• .de (Germany)
• .jp (Japan)
• .cn (China)

Some ccTLDs have been repurposed for commercial use, such as:

• .io (British Indian Ocean Territory, popular among tech companies)
• .tv (Tuvalu, used by streaming/television services)

Sponsored Top-Level Domains (TLDs)

Designated organizations manage these specialized domain extensions and typically serve specific community purposes. Examples include .edu for educational institutions and .gov for governmental entities.

• .aero: Reserved for the aviation industry
• .museum: Exclusive to museum institutions
• .coop: Designated for cooperative associations
• .jobs: Specifically for human resource management

New gTLDs

New generic top-level domains have recently expanded the domain name system, including more specific and descriptive options like .app, .shop and .blog.

• Industry-specific: .photography, .technology, .construction
• Geographic: .london, .berlin, .nyc
• Generic terms: .online, .digital, .website
• Activity-based: .shopping, .dating, .gaming

Brand TLDs

Select organizations have acquired their unique top-level domains, such as .google or .amazon, allowing for complete control over their digital naming ecosystem.

• .google (Google LLC)
• .amazon (Amazon Inc.)
• .microsoft (Microsoft Corporation)

Each domain type operates under specific registration policies and technical requirements established by ICANN (Internet Corporation for Assigned Names and Numbers) and respective registry operators.
