DNS Management

The Domain Name System (DNS) is a technology that converts website addresses (domain names, for example internet.am ) opened in your browser into a digital representation - IP addresses (for Internet.am IP address is 167.86.91.28). This is necessary because computers understand only numbers, in other words, DNS works like a translator, translating from a human-readable language (website names) to a computer-readable language (IP addresses).

How Does DNS Work?

The Internet connects individual network nodes using a special TCP/IP protocol (network communication language).

Under this protocol, each device connected to the Internet is assigned its own unique address, called an IP address.

Communication and data exchange on the Internet is carried out precisely with their help, any data request is sent to a specific IP address.

The DNS is coordinated by ICANN, an organization registered in the United States.

The basis of the global domain name system are root DNS servers, thirteen in total, 11 of which are located in the US, one in Sweden and one in Japan. Their purpose is to maintain an up-to-date list of top-level domains. Top-level domains include, in particular, .հայ and .am domains.

The DNS System Includes Client and Server

A DNS client is an application on a computer or mobile phone that requests information from a DNS server.
The DNS server responds to DNS requests. It can independently store the necessary data or redirect further requests, depending on the purpose and specific request.

What is a Resource Record?

The information itself is stored in the DNS in the form of resource records.

Resource records are divided into several types, each of which has its own purpose. For example, records of type A define the relationship between a name and an IPv4 address, records of type AAAA record the relationship between a name and an IPv6 address, and records of type MX are used to identify the mail server serving a domain. This means that the website can be hosted on one IP address and the mail server hosted on a different IP address, such as Google.

DNS Queries

Recursive queries are designed to search for information in a distributed DNS system.
Non-recursive queries look for information on only one specific DNS server. They ask it to return either an IP address for a specific domain, or the address of a DNS server that serves the domain.

Accordingly, there are DNS servers on the Internet that support recursive client queries for information about any domain name. This feature is usually supported by the DNS servers of the ISPs serving users.
