Today we'll discuss domain names, which are closely related to hosting. A domain name is a set of characters used to identify network nodes and resources such as websites, email, file exchange services, and databases. For example, dnray.com is the name of a site hosted on a server with an IP address of 91.228.155.94.



The DNS service was introduced to make it easier to remember network nodes by assigning them symbolic names. A domain zone is a large domain that contains domains of a certain level, such as first-level domains like .DE, .COM, .ORG, etc. or all the variety of addresses within the domain of the second, third, and N-level.

There are three types of domain zones: gTLD (General Top Level Domain), ccTLD (Country Code Top Level Domain), and IDN (Internationalized Domain Names). To get a domain for use, you need to contact a domain name registrar, who can be accessed directly or through an intermediary like a hosting company.

Some companies price their domains two to three times higher than the registrar's price tag, but most hosting providers offer domain registration as a complementary service with a symbolic profit margin.

When a domain is registered, it is typically done so for a period of one year and the domain needs to be renewed after that time. Registrars actually rent out domains rather than selling them. Each domain zone has its own set of rules for registration and maintenance, with some requiring specific documents or having industry-specific requirements for registration. While there are no official restrictions for registering a domain in a certain zone, it's important to be mindful of nuances that may occur. If you have any questions about domain registration, feel free to ask in the comments.

Great job, and thank you for creating accessible material in the IT field. When I was studying at university, it was difficult to find clear and concise information on the topic. I had to piece together information from various sources of varying degrees of clarity. It's refreshing to have access to a resource that is both comprehensive and easy to understand.

There is a lack of information available on domain names today, despite their close relationship to hosting. While the topic may seem of mediocre relevance to hosting itself, it is essential for identifying hosts and the resources and services they offer, including websites, email, file sharing, and databases.

When it came to choosing a domain, simplicity and convenience were key for me. A SEO specialist I know advised me not to get too clever with the name, and I'm glad I took their advice. Having a straightforward and easy-to-remember domain makes it easier to promote through search engines.

Thanks for the interesting propaedeutic post! I recently started to study this topic, so for me it is very useful! However, I did not quite understand the allusion to a company with inadequate pricing, is that a "monster" Google?

Domain names play a pivotal role in the internet ecosystem as they provide a user-friendly way to access various online resources, including websites, email services, and databases. The Domain Name System (DNS) acts as a critical infrastructure, allowing domain names to be translated into IP addresses, which is essential for efficient communication and interaction across the internet.

Domain zones are large segments of the domain name space that include specific levels of domains. Top-level domains (TLDs) are a significant part of domain zones and can be categorized into three main types: generic top-level domains (gTLDs), country code top-level domains (ccTLDs), and internationalized domain names (IDNs). gTLDs encompass generic domains like .COM, .ORG, and .NET, while ccTLDs are specific to particular countries or territories, such as .DE for Germany. IDNs support domain names in non-ASCII characters, allowing for the representation of multilingual domain names.

To obtain a domain, individuals or organizations typically engage with a domain name registrar, either directly or through a hosting company. Registrars offer domain registration services for a fee, usually on an annual basis, with the requirement for renewal after the initial registration period. It's important to note that the registration process effectively involves renting the domain rather than owning it outright.

Each domain zone has its own set of rules and requirements for registration and maintenance, which may include specific documentation, industry-specific regulations, or unique restrictions. While there are generally no official restrictions for registering a domain in a certain domain zone, it's crucial to be aware of the specific guidelines and nuances associated with each zone.

Navigating the domain registration process can be complex due to the varying rules and requirements across domain zones, and it's advisable to seek guidance from a knowledgeable source to ensure compliance and successful registration.
