domain

A domain or domain name is the address (name) to get to the site. Each domain name is unique and cannot be used on multiple sites or duplicated. That is, if you buy a domain for your brand, it remains only with you and no one else will be able to use it.

On this website of the web design studio, the domain name is sheina-aleksandra.ru.

The domain name influences the further promotion of the site, so its choice is very important.

Domains were invented to make it easier for users to find the resources they need.

Computers exchange data using IP addresses — this is a string of 4 numbers (octets) separated by dots; these numbers encrypt information about the location of the server where the site is stored.

All domain names are tied to an IP address. Since our sites are stored on Tilda servers (it is worth noting that Tilda has several of them around the world), but if we are talking about Russian sites, then our IP is 185.215.4.12.

When you enter the domain name of a site in your browser, DNS (Domain Name System) servers convert the name into an IP address and establish a correspondence between the domain name and the IP address, and you are taken to the desired site.

If a site is moved to another server, its IP address changes, but the domain remains the same.

By domain you can go to a website or find it in search engines. The simpler the name, the higher the likelihood that it will be entered into a search or that it will appear in higher positions in search engines.

Domains earn a reputation in search engines over time, so you need to think carefully about choosing a domain at the very beginning, so as not to change it later, because. if you leave the site but change the domain, your position in search engines will be reset.

You can configure corporate (domain) email by domain. For example, for us it is info@sheina-aleksandra.ru, such emails look more presentable when sending out newsletters and immediately make it clear who the letter came from.

A domain name consists of several parts, separated by dots. These several parts form a hierarchical structure in which the domain levels are listed from right to left.

The zero-level domain is the root domain, highlighted in red. Invisible to users, but needed for the DNS system to work (marked with a dot that is not displayed in the browser).

First level domains are also called domain zones. There are 2 main types:

1. National top-level domains. A group of domains that determines whether a site belongs to a country:

• territory of Russia — .ru,
• Germany — .de,
• Georgia — .ge,
• UK — .uk, etc.

2. Generic top-level domains. Domains that determine the theme of the site:

• commercial organizations — .com
• information sites — .info
• business structures — .biz
• personal sites — .name
• non-profit organizations — .org

Second-level domain, main domain — the name of the site, a unique name invented by the creator. The combination of the main domain and domain zone must be unique. For DNS, the domains sheina-aleksandra.ru and sheina-aleksandra.com are 2 different domain names. Therefore, for the future of development, it is recommended to purchase all possible domain variations at the beginning in order to gain advantages in search results.

Third level domain, subdomain. Based on a second level domain.

Basically, subdomains are used to logically divide a website into parts. Sites on subdomains become independent resources and acquire all the properties of a separate site.

There are also domains of the fourth, fifth and subsequent levels of domain names, but they are extremely rarely used, because The site name becomes too long and difficult for users to enter and remember.

The domain name can consist of letters, numbers, hyphens and lowercase letters (DNS is not case sensitive).

General rules:

• name must be unique
• cannot begin or end with a hyphen
• cannot contain 2 hyphens in a row
• cannot contain spaces or underscores

In fact, you do not buy a domain, but register it, that is, you rent the chosen name for a period of one to 10 years. The lease can be extended.

The lease duration and renewal procedure depend on the selected domain zone. The necessary information for each domain zone can be found on the domain name registrar website.

If your domain lease has expired and payment has not been received, most often the owner has about a month to renew; when this period expires, the domain will become free again and someone else can purchase it.
