What is a second-level domain (SLD)?

A second-level domain (SLD) is a component of a domain name that is located directly before the top-level domain (TLD). It represents the main part of the domain and typically contains the organization's name, brand, or other identifying information.

Based on the example 365.hosting:

  • "365" is the second-level domain.
  • ".hosting" is the top-level domain (TLD).

The second-level domain can be unique and helps identify a specific website or organization on the Internet. It may reflect the company's name, product, service, or keywords related to the domain owner's activities.

Here are some other examples of second-level domains:

  • google.com (where "google" is the second-level domain)
  • apple.com (where "apple" is the second-level domain)
  • amazon.co.uk (where "amazon" is the second-level domain)

Second-level domains can vary in length and structure depending on the preferences and requirements of the domain owner. They serve as an important identifier on the Internet, helping users determine which website or organization is associated with a specific domain name.
