What is DNS

First of all, DNS is an acronym that stands for Domain Name System. DNS is a domain name system that links domain names to numeric addresses.

You can use the registrar's DNS to park the domain, but usually the DNS of the purchased hosting is set immediately and the rest of the parameters are already configured there.

However, you can set any DNS, and not use the standard ones. Why change DNS ? Typically, standard DNS offers modest features, so you can switch to advanced DNS. For example, changing DNS can be useful for various operations: when needed make mail for a domain , for faster loading of the site, for more convenient management of records, etc.

DNS from Yandex

You can choose DNS from Yandex - this guarantees fast loading of the site and security. It is enough to delegate the domain to Yandex servers ( dns1.yandex.net, dns2.yandex.net ) and add the site to the domain control panel, after which you can perform any operations with DNS records there. By specifying an NS server, the control of all records is completely transferred to this server. Yandex also has a DNS service for ordinary users (DNS for PCs, routers, routers, etc. - they filter content and protect against threats), which should not be confused with DNS for sites.

Thus, we have covered, what DNS is and what it is for . You may also find it helpful to know the types of DNS resource records and which DNS to choose for your site.
