A TLD, which stands for a top-level domain, like .com, is the final segment of a domain name. ccTLD, a country-code top-level domain, falls under the category of TLDs and shows a specific country. Examples of ccTLDs include .in, .de, .mx, and .fr. A gTLD, which refers to a generic top-level domain, is the most commonly used type of domain name. This is because it includes popular domains like .com, which has more registrations than all the country-specific domains combined (ccTLDs). Historically, the main gTLDs were .com, .org, .net, .edu, .gov, and .mil, but the number of available domain extensions is growing with the addition of newer TLDs like .online, .xyz, and .name.
