caching records from other DNS servers.

We have dealt with the first task, now we will explain the second one - why is record caching necessary and what is it.

The relationship between a domain and an IP address has to be clarified every time you visit a website. Imagine that the website you want to visit is located on the other side of the country. Frequent requests to a distant primary DNS server can take a lot of time and slow down the resource loading speed. To protect users from long waits, the DNS server closest to your computer (in most cases, it is located at your Internet provider) stores data on IP addresses that have already been requested before. Thus, when you access the same web resource a second time, it will return its address much faster, since it will already have it in its cache. This saves a lot of time.

How to register a domain name
To register a domain, you need to come up with one. However, in the modern world, many domain names are already taken, so we recommend experimenting with domain zones and interesting names. Remember that the domain should be simple and memorable.

You can select a domain name in "Eurobyte" through the control panel. To do this, register and go to the "Domains" tab. You can read more about domain registration on the page.
In order for the domain name to start "working", the client must provide the registrar with the domain name of the DNS server, which will contain all the necessary data about the registered domain. For example, when transferring a domain to the Eurobyte hosting, the following NS servers must be specified:

ns1.eurobyte.ru;
ns2.eurobyte.ru;
ns3.eurobyte.ru;
ns4.eurobyte.ru.
What is a DNS zone?
In this section, we will explain in detail what a DNS zone is. This definition bosnia and herzegovina whatsapp number database is important for a deeper understanding of how the Domain Name System works. Above, we talked about a simple version of the relationship between a domain and an IP address: 1 domain name = 1 website = 1 IP address. But a specific domain may be associated not only with a specific website, but also, say, a mail server. And their addresses may differ. All possible relationships between domains and IP addresses are located in a special file stored on the DNS server. The contents of this file are called a DNS zone description or simply a DNS zone. It may contain records of different types.

Some more facts
One domain can correspond to multiple IP addresses. This measure serves to increase the reliability and speed of the resource.
One IP address can also correspond to more than one domain name. Today, there are more than 1.5 billion websites. And this number is constantly growing. In this regard, the four-digit IP address has become a scarce resource. In order to save money, one server can host multiple websites with different domains, which are assigned one IP address. The web server, having received a request, analyzes the domain name and directs it to the desired website.
Conclusion
Thus, the domain name system is needed to match domains and IP addresses. In "Eurobyte" you can not only buy hosting, but also register a domain name. The price for domains starts from 179 rubles per year. If you have any questions, ask them in the comments. Our specialists will try to answer as soon as possible. Thank you for reading!
