The abbreviation gTLD stands for “Generic Top Level Domain.”
A Top Level Domain is the highest realm of administrative authority within the Domain Name System, and is represented by “domain extensions” like .com.
There are two types of Top Level Domains — country-code (ccTLD) like .us and .ru, and generic (gTLD) like .com and .org.
Some ccTLDs are commonly used as if they were actually generic TLDs, such as .ly (Libya), .me (Montenegro), and .tv (Tuvalu). Also, a few gTLDs are reserved and not available for use by the general public, like .gov and .edu.
