The letters displayed after the last dot of a domain name \u2014 such as .ca, .us, .org, .net and .com \u2014 are the TLD (top-level domain)<\/strong>. It is therefore the most general component of the domain name. <\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

All domains are sub-domains of each other, except for the root (which is the beginning of the domains, so to speak). For example, abc.xyz.ca<\/strong> is a sub-domain of .xyz.ca<\/strong>, .xyz.ca<\/strong> is a sub-domain of .ca<\/strong>, and .ca<\/strong> is a sub-domain of the root.<\/p>\n\n\n\n

There are three types of TLDs:<\/p>\n\n\n\n

  • Country code TLDs (ccTLDs).<\/li>
  • Generic TLDs.<\/li>
  • Special-Use TLDs.<\/li><\/ul>\n\n\n\n

    Country code TLDs<\/strong> are associated with specific countries in that their subdomains share a common geographical characteristic.<\/p>\n\n\n\n

    Generic TLDs<\/strong> belong to ICANN. They are intended to host subdomains with a common non-geographic characteristic. Generic TLDs (or domains) can be “open<\/strong>” or “closed<\/strong>“. The open TLDs .net, .org, and .info are well known.<\/p>\n\n\n\n

    Special-Use TLDs<\/strong> have special features. One example is .arpa<\/strong>, which is used to solve infrastructure problems.<\/p>\n\n\n\n

    Types of TLD<\/figcaption><\/figure><\/div>\n\n\n\n

    Open and Closed Generic TLDs<\/strong><\/h2>\n\n\n\n

    Open<\/strong> TLDs have no restrictions. These TLDs have no specific fields, with a few exceptions.<\/p>\n\n\n\n

    For example :<\/p>\n\n\n\n

    • .app<\/strong> and .dev<\/strong> managed by Google must absolutely have the SSL (Secure Socket Layer) security protocol for them to be valid.<\/li>
    • .areo:<\/strong> you must be registered with an aeronautical order to register a domain name with this TLD.<\/li>
    • .travel:<\/strong> you need an agency number to register a domain name with this TLD.<\/li><\/ul>\n\n\n\n

      Users who want to obtain subdomains in the category of closed<\/strong> (also called restricted) generic TLDs must comply with certain specific rules (or policies).<\/p>\n","protected":false},"excerpt":{"rendered":"
