Another of the exciting topics, although at first glance it may seem that domain name is a banality. But believe me, it's not quite like that.
But first, let's explain what a domain is. Simply, it is the text name of your website on the Internet (, which points to the hosting company's server where you have stored all the digital data of your website.
However, if we want to explain it exactly, it is a text representation of the server's IP address to which the visitor connects when surfing the Internet. The IP address contains only numbers and periods. It can look, for example, as follows: 195.572.43.1. But can you imagine writing IP addresses instead of It would be challenging to remember.

Domain names most often contain letters, numbers, dots, hyphens, or a combination of both. For example,,, and so on. Information about which IP address each domain should point to is stored in DNS (Domain Name System) servers.

We distinguish domains according to levels:

  1. first-level domains, we also call them TLDs (top-level domains). They can be generic (.com .net .org .edu ...) or national (.us .au .eu ...)
  2. second-level domain, this is the name of your domain + TLD. In my case, it's My site is on a second-level domain.
  3. third-level domains or called subdomains, their management or creation are under the domain owner's administration. Many companies or bloggers use them, for example, if they want to set up an online store to sell merchandise and want to have it separate from their main website. For example, if I wanted to make an e-commerce shop and sell merch on and I would like to use a subdomain for it, it would look like this: (shop. is a subdomain). The advantage of a subdomain is, all the data are in different directories. In case of a problem, your main page is not affected. For example, there is a situation: I have my blog on the domain My eCommerce shop is on the subdomain I made modifications to the eCommerce shop, and something went wrong, so the shop did not work and broke the whole page on the subdomain, but I can't fix it, and I have to delete it. But I'm lucky because he was on a subdomain, and with my blog happens nothing. Many bloggers use subdomains to disrupt a well-established blog if they do not want to register a new domain to sell merchandise because no one wants to risk (despite backing up their site) to ruin their perhaps several years of work.

As with article hosting for WordPress, there is an incredible number of domain resellers on the market. They differ mainly in the price per domain (the differences can sometimes be huge) and other services. But what services can there be when selling domains? For me, one of the most important, if you want to avoid spamming your e-mail box in the future and protect your data as a domain registrar, is WHOIS protection.

Don't know WHO.IS is? That's okay. I didn't realize it before either.
WhoIs is not just a fancy phrase. WhoIs is a programmer's query to the database to determine who is responsible for the domain or IP address.

It means that if you are going to register your domain with any registrar, you must provide personal information about the person or company that is going to register the domain. Name, Surname, Address, Company name (if you register the domain as a company), e-mail, telephone number. This data are in the ICANN database (International Corporation for Assigned Names and Numbers). The data are available both on ICANN and in the WHOIS database, and anyone who has access to the Internet and knows your domain name can find out who owns it.
Whois is a database of all domain names in the world. Of course, spammers as well. They use automated software to obtain your data - but they are most interested in your e-mail. Usually, when registering a domain name, everyone lists the primary e-mail they use. However, ICANN tries to prevent automatic data downloads by security via Captcha or restricting searches from a single IP address.

Did it also happen to you that suddenly you started getting a lot of spam? It's because your e-mail address is on the list of spammers, and they began their work. Send thousands of e-mails for one purpose only: to make money from you (sending various offers for products or services. In the worst case, try to get to the details of your credit card or internet banking. They use very sophisticated methods - the main thing is to click on their link in an e-mail you received in your inbox (we can discuss this in more detail in another article).

How to prevent it? There are two options:
1. You can purchase a paid service directly on the site - WHOIS Protection for 25 USD for one domain directly on WHO.IS
2. Register a domain through a service that allows this directly during registration. Some registrars (NameSilo for free) have it for free included in the domain price, and others for extra pay for this service each year (prices for this service may vary).

I use the second option. As I wrote above, there are many domain registrars, and many also offer hosting and vice versa (all hosting providers offer the option of domain registration. Many times the prices per domain are high or do not provide the WhoIs service. It is also customary that if you buy hosting, you have a free domain for a year, but I do not use these services. I buy domains separately and hosting separately).

What reseller do I use for registering a domain name?

I use to register domains. Why? Fair price for domains (see prices for domain name), WhoIs included in the price of the domain, good and simple administration, and creating a logo (free service). After editing, the DNS records are changes within a few minutes. If you are buying domains separately and hosting separately, you must change the domain's DNS records. If you don't change it won't know how to assign hosting to the domain, and your site won't work (at the end of the article are step-by-step instructions on how to change DNS in a few minutes).

Checkout page in Namesilo. How you can see below WHOIS protection is for free.
