What is a top and second-level domain?

A domain name is typically composed of two main parts: the top-level domain (TLD) and the second-level domain (SLD). These components work together to create a complete and unique domain address on the internet.

Top-Level Domain (TLD):
The top-level domain is the highest level of the domain hierarchy and is located at the end of the domain name. It is also sometimes referred to as the domain extension. TLDs are classified into two main categories: generic top-level domains (gTLDs) and country code top-level domains (ccTLDs).
Examples of generic top-level domains (gTLDs) include:

.com (commercial)
.org (organization)
.net (network)
.edu (educational)
.online(business)
Examples of country code top-level domains (ccTLDs) include:

.in (India) Eg: Hostinghome.in
.uk (United Kingdom)
.ca (Canada)
.jp (Japan)
.au (Australia)
.us (United States)
Second-Level Domain (SLD):

The second-level domain is the part of the domain name that appears before the top-level domain. It is the name chosen by the owner of the domain and is used to identify a specific website, organization, or entity.
In the domain name “example.com”:

“example” is the second-level domain
“com” is the top-level domain
Together, the second-level domain and the top-level domain create a complete and unique domain address. The combination of these two components helps users locate and access specific websites and online resources on the internet.
