a Top Level Domain (TLD) is a domain at the highest level in the hierarchical Domain Name System of the Internet. TLDs are generally categorized into two main groups:
gTLDs. gTLDs are generic TLDs and the most common are the .com, .net, .org, etc. While it used to be that there were only a handful of extensions available, there are now numerous customized TLDs to choose from to have it be specific to a particular brand, industry, or type of service offering.
ccTLDs. ccTLDs are country code TLDs and the extensions are limited to specific countries. Countries and territories have a top-level domain name available that’s based on the country’s two-letter ISO code — for example .us.
In a previous blog, we explored the important differences between base domains and full path URLs. In this post, we wanted to take a step back and cover the basics—the individual structural elements of a URL (Uniform Resource Locator).
