gTLD (generic Top Level Domain) is a domain assigned to ccLTD in a specific area and field, and is given to all people in the world.
Unlike ccLTD, there is basically no local restriction and it can be obtained from any location in the world. Basically, like ccTLD, it is managed by ICANN and assigned by a registrar. There are currently 22 gTLDs (as of March 2016). Major places include “.com”, “.net”, “.gov”, “edu”, etc.
