What is a domain name

The domain or domain name is simply the internet address of your website, for example www.nuclear.hosdting. Each domain corresponds to a series of numbers. IP addresses (eg 1.1.1.1). It is always unique, so there can not be two identical domains.

We generally divide the domain into three levels. Individual levels are separated by a dot.

First (TOP) Level Domain

First-level domain or Top-Level Domain, abbreviated to TLD. This domain is at the end or end. after the last dot. TLD domains are divided into two types:

  • Geographic - ccTLD
  • Generic - gTLD

Geographic ccTLD

These domains are assigned to individual states. As a rule, they are in the form of an abbreviation for the country, for example, .UK for the United Kingdom, .SK for Slovakia, and so on.

Generic gTLD

You can register these domains completely, they are general domains that are not associated with any state. (e.g., com, org, net). New registrations are now open for new gTLD domains (such as free, blog, party, movie, live, and more).

Domain of the 2nd level

The 2nd level domain is a sequence of unique characters behind the national or generic domain. This domain is paid and must be registered. In this domain, only the English keyboard characters and only a small part of the ASCII characters can be used. The maximum domain length is 63 characters.

There are exceptions, domains that can contain special characters called IDN (Internationalized Domain Names). These domains contain special characters as a result, but they convert to a sequence of common characters in the background.

Domain of 3rd level

We also call it a subdomain. The subdomain expands the second order domain. And so you can use the subdomain, you must be the 2nd order domain owner. No 3rd level domains are charged. The domain is in the form of, for example, subdomain.my-domain.com, but also www.my-domain.com.

If you have DNSSEC enabled on your domain, delete all set DNS keys together with the nameserver change!

Why to use our NameServers?

  • In our nameservers, all DNS records needed for properly services operation are automatically set up correctly.
  • Using our nameserver reduces the risk of possible service malfunctions.
  • Some services or features may be available only if you use our nameservers, such as automatically DKIM settings, automatically SPF settings, DNSSEC, cloud webhosting features and more.

Changing DNS records separately

If you do not have the ability to change DNS name servers, you can set individual DNS records. You can find the values for the settings in the control panel on the home page. However, we do not recommend this solution.
