Some facts#

  • Domains allow to avoid using hard to remember IP addresses in favor of words that are easily understood by people, e.g. calculla.com.
  • Domains consist of two parts separated by a dot:
    • the proper name - e.g. calculla, this part is created as a result of registration of the chosen name by the concerned entity,
    • ending postfix - e.g. .com, the list of acceptable endings is limited to a fixed pool, so they are not subject to registration.
  • In the early phase of internet era the pool of so-called functional domains was established. It was designed to organize the internet based on the main purpose of the domain. The original list of functional domains is:
    • .com - domains intended for commercial applications,
    • .org - Nonprofit domains
    • .net - domains for computer networks,
    • .int - domains intended for international organizations,
    • .edu - domains intended for scientific institutions,
    • .gov - domains reserved for the US government,
    • .mil - domains reserved for US military use.
  • Currently, the above assigment is conventional, and the original assumptions have blurred. In practice, most domains can be registered by any entity. Only the following domains are still reserved to particular type of entities: .gov, .int and .mil.
  • In addition to functional domains, regional domains were introduced. They were supposed to organize the internet in geographical terms.
  • Regional domains coincide with the two-letter ISO 3166-1 country codes, e.g. ending .pl means Poland, .de Germany, etc. Exceptions to this rule are:
    • .eu - domains designated for the European Union collectively,
    • .uk - domains for UK (uk instead of gb).

What is the meaning of each calculator field ?#

  • domain - simply one of the so-called internet postfixes e.g. .com in the address calculla.com,
  • assigned entity - for whom, in the creators assumptions, the domain is intended, but most domains can be registered and used without restrictions, and the divisions are only contractual,
  • support for non-ASCII characters - if it is possible to register a domain with international diacritical marks, e.g. łabędź.pl, if you want to learn more about IDN domains and how to code them, you can visit our other calculator: Punycode encoding (IDN)
  • support for DNSSE - if the domain supports DNSSEC (DNS Security Extensions) increasing security,
  • possibility of registering a second-level domain - if it is possible to register a direct subdomain (e.g. calculla.com), otherwise only third-level domains (e.g. calculla.co.uk) can be registered,
  • support for the IPv6 protocol - if the domains allow to work with version 6 of IP protocol.
