Each site differs from others in its name. The web site’s domain is its unique name. Domain name consists of several parts. By way of example we will consider the domain of our web site https://unproof.com/

• Аs you can see the name starts with the abbreviation  https (Hypertext Transfer Protocol Secure) or www. (world wide web). The abbreviation http (hyper transfer text protocol) is older and not secure.
  Websites under https (Hypertext Transfer Protocol Secure) use SSL (Secure Sockets Layer) which is a protocol for establishing secure links between networked computers.
  These Internet formats are used according to standard. Their content is quite large, so the more curious ones of you could search a little more info about them on the web. I mentioned them from the point of view of their function, namely, that after them follows the real name of the website.
• way – this is the real part of the domain. It may be in Latin (over 99 %) or in Cyrillic (not recommended). The name should display what is the destination of the site or a play upon words.
• .in.net – This is the domain extension. The extensions are several dozen, but most used are: com; info; org; biz; eu. The choice depends on your desire, as well as on the option whether the chosen domain is still available, i.e. It is not taken by somebody else. An interesting fact is that all possible combinations of 3 letters with .com have been busy for long time.

When you choose the domain, have in your mind that it should be memorized easily by the users. The shorter domains are easier to remember.
The domain could be a combination of numbers and letters.
The only character which is allowed between the letters is “-“ (dash). For example:
www.rumi-woodcarver.eu

The fee for using the domain is paid usually with the fee for the hosting service, to companies that are representatives of the real owners of the domain rights.
The web company that offers such services is called hosting company. It is desirable this company to be well-known and stable.
An important point in choosing a domain is its compliance with the remaining steps in building a web site – Internet – Marketing, dendriform structure, the used keywords, “The Content Is the King”, promotion and SEO Optimization, the use of Advertising channels and PR campaigns, and as well as the overall administration of the web site. The interesting web design is what they will see, but the name is what will remain in the users’ mind – so choose carefully!
